Margo the Z Bomb

San Francisco Call Bulletin, 26 December 1953, 8

Margarita Mercado, is the Puerto Rican dancer, who appears as Margo the Z Bomb in 曼波女郎 Mambo Girl, the 1957 movie musical from Hong Kong. She performs a floorshow at the 麗池 Ritz nightclub at North Point on Hong Kong island, accompanied by the percussionist, Ollie Delfino, with Freddie Sotelo leading the band; both musicians were from the Philippines. 

Mercado made her professional debut in New York, dancing at the Havana-Madrid nightclub on Broadway, and then spent three years touring Mexico and South America with the Cuban bandleader, Pérez Prado—the ‘King of the Mambo’—before moving to San Francisco. 

She is introduced first as Margarita Mercado at San Francisco’s Sinaloa Club in December 1953, where she soon becomes billed as ‘Margo the Mexican Z Bomb – The Absolute End!’ – later shortened to ‘Margo the Z Bomb’.

Mercado performed in San Francisco until October 1954, when she embarked on a tour across cities in Asia and the Pacific. For the next three years, she toured extensively between Saigon, Phnom Penh, Bangkok, Singapore, Kuala Lumpur, Hong Kong, Manila, Tokyo, Sydney, Melbourne and Honolulu. By the time she filmed the sequence at the Ritz nightclub in Hong Kong, around December 1956, Mercado had been touring with Delfino for two years. 

Mercado’s working partnership with Delfino was reported on her arrival in Hong Kong from Tokyo in July 1955; in fact, the newspaper article suggests that they were travelling together. They must have teamed up in Manila, soon after Mercado’s arrival in November 1954, and then toured the region extensively together.

I write about the partnership between Mercado and Delfino in ‘Transporting Variety Through the Nightclubs of Hong Kong’, chapter 2 of Touring Variety in the Asia Pacific Region, 1946–1975 (Palgrave Macmillan, 2020).

Here are some documents about Mercado’s touring and an incomplete timeline of her career, 1953–1964.

Margo in Manila, November 1954

‘Z-bomb hits Circus Room today’, Manila Times, 6 November 1954, 11. – Margo, sensational show girl popularly called the “Z-bomb,” will be presented for the first time in Manila tonight, Saturday, November 6, at the Circus Room, according to Manager Bill Burr. A twenty-two year old Puerto-Rico-born American citizen, Margo is fresh from a triumphant three-year tour of South America, Central America and Mexico, with Perez Prado, “King of the Mambo.” The sexy show girl has also been featured at the world-famous Sinaloa, San Francisco’s (U.S.A.) outstanding restaurant-night club, where she broke all existing records during her spectacular run by causing crowds to stand nightly outside the night spot, waiting to be admitted.

Biography of Margo the Z Bomb, publicity brochure, c. 1957

This biography of Margarita Mercado is included in a publicity brochure, c. 1957, held in the Tivoli Theatre collection, State Library of Victoria, MS 11527, Box 33. At the time, her manager was Leonard Saffir.

Margo the Z Bomb, Pix, 15 February 1958

Margarita Mercado was born in Puerto Rico, twenty four years ago. When she was three, she moved and settled down in New York City where she attended grammar and high school.

In her early teens she was performing at home in front of her mother and family friend Chuchu Montalban, brother of movie actor Ricardo Montalban. He saw the possibilities of Margarita as a stage star and soon she made her debut on Broadway at the famed Havana Madrid nightclub.

After New York City, Margo was swamped with contract offers and accepted on which took her on tour in Canada, Boston, Philadelphia, Baltimore and Washington. She then joined mambo King Perez Prado and was quickly billed as the Queen of the Mambo. Success after success followed Miss Mercado and Prado for three years while on tour in South America, Central America and Mexico playing all the leading nightclubs. She was featured in twenty motion pictures while South of the Border.

From Mexico, Margarita moved to San Francisco and starred at the world famous Sinaloa, one of the top California nightclubs. San Francisco critics called her the fastest thing on heels and the hottest act to hit the city in years. It was there she shortened her name to Margo and added the ‘Z-Bomb’ title as pinned on her by a leading nightlife critic.

Hawaii was next for the wonder dancer, followed by a comprehensive tour of the Far East taking in the Philippines, Hong Kong, Vietnam, Cambodia, Thailand, Malaya, Formosa and Japan.

Margo in Tokyo, 1957, with plans for her publicity in Melbourne

This letter from Mercado’s manager, Leonard Saffir, was addressed to David N. Martin, managing director of the Tivoli Theatre, Melbourne, while they were in Tokyo, in July 1957. It is held in the Tivoli Theatre collection, State Library of Victoria, MS 11527, Box 33.

[Letter, dated] July 17, 1957. 

[From] Leonard Saffir, Foreign Correspondents Club of Japan, No 8, Marunouchi, 2-Chome, Chiyoda-Ku, Tokyo. 

[To:] Mr David N. Martin, Room 652, Nikkatsu Hotel, Tokyo.

Re: Margo Publicity

Dear Mr Martin

As we discussed in your hotel suite today, I would now like to outline to you my idea on a publicity cocktail party for Margo. These are my suggestions and certainly may be passed to your PR department for approval, changing, etc. I think, however, it is the ice-breaker and key to a good publicity campaign.

  1. As soon as possible after Margo’s Sydney arrival a cocktail party in her honour should be held at a hotel or nightclub. 
  2. Printed, engraved invitations should go out (several days before) to as many newspaper, radio, television, etc., people in Sydney at the time. These should include persons from the copyboy to the managing editors etc., and should not be only those connected with entertainment. 
  3. In addition invitations should go to a few Tivoli performers and any other celebrities in town (even if not Tivoli); and a few city and government officials.
  4. Host of the party should be either David N. Martin or Leonard Saffir or both and suggest invitations read something like this: Mr David N. Martin, managing director Tivoli Circuit and Mr Leonard Saffir, manager of Margo the Z Bomb requests the honor of your presence at a reception to meet the world famous singer-dancer at etc…
  5. Gifts for the press members (I hope to have cigarette lighters with Margo’s name and characture [sic] on) I hope will be ready and handed out; also Margo brochures available.
  6. A combo (preferably one with a trumpet player) should be playing throughout the party, but not show music.
  7. After about two hours of free (and there should be plenty of it) liquor, someone planted in the crowd should ask Margo (impromptu) to do a number. Lady-like she’ll refuse but applause will force her on. I’ll have the music in my briefcase (or someone) and will be passed to band members. One number (Cherry Pink) is sufficient; the band may or may not rehearse an hour before the party. 

The main idea of this party, I believe is not to ask for anything from the press but just to give them a good time and a good party. I’ve seen newspaper men all over in my 10 years writing and none is different. 

This cocktail party in the long run will pay off more than the formal press conference. The boys after this one will then go after pictures, interviews, etc. 

In addition, I assume the press photographers, etc., will be tipped off at Margo’s estimated time of arrival at Darwin and Sydney.

I would love to know if these plans for Margo’s ‘impromptu’ performance at a cocktail party in Melbourne actually happened! ‘Cherry Pink and Apple Blossom White’ was a hit for Pérez Prado and his Orchestra, released in 1955.

  1. Yes Margo Z Bomb did dance at the cocktail party–I was soubrette in the show she was going to star in at the Tivoli and some of us were invited to attend —

  2. That’s brilliant, Patti – I’m so pleased to learn there was a cocktail party for Margo in Melbourne. Now I wonder… where was the party held?

  3. Hi! My name is Margarita Heredia Mercado, I’m the daughter of Margo Z Bomb (Margarita Mercado Lamboy) I would love to know how you know my mother’s story, my father was who found about this article, he is 87 years old, my mother sadly passed away in 1996. Love to hear from you. Thanks!

  4. Hi Margarita! Thanks so much for your message. It’s an honour to be in contact with you. I am sorry to learn that your mother passed away. I learned about her wonderful career when I was writing a book about artists who toured the Asia-Pacific region in the 1950s and 1960s. I was interested in finding out where she performed while she was on tour in the region. Most of what I know comes from newspapers in San Francisco, Hong Kong and Melbourne, Australia – along with her amazing performing in the Mambo Girl film. I can send you what I’ve found if you like. I’ll be in touch by email. Best wishes to you and your father, Jonathan
