Havana's famed Tropicana nightclub has turned 70, its glamour days as an international celebrity haunt well behind it, but its future assured as a money-making hotspot for the cash-strapped Cuban government.

Scantily clad female dancers, their costumes mostly feathers and sequined thongs, writhed across its outdoor stage as they have for decades in a show that began on Monday night and ended Tuesday morning (local time), marking the club's opening on December 30, 1939.

The show included an homage to stars like Carmen Miranda and Nat King Cole who performed amid Tropicana's lush gardens and towering trees.

Photos of Cole flashed on screens behind the stage as two dancers swayed romantically to his song Tenderly.

Tropicana began as a casino and nightclub that, especially in the decade before Cuba's 1959 revolution, attracted a steady stream of celebrities ranging from Marlon Brando to Maurice Chevalier. Some performed there and others simply mingled with the elegantly dressed clientele.

Their presence and the accompanying publicity made Tropicana one of the world's best known nightspots.

At the time, Cuba, just 145 kilometres from Florida, was a popular tourist destination for Americans, who have generally been banned from travelling there under a US trade embargo in place since 1962.

Cuban gambler Martin Fox owned the club from 1950 on, but its casino, like many others in Havana at the time, was run by an associate of Santo Trafficante, a Florida mobster who had extensive holdings in Cuba.

After Fidel Castro and his bearded rebels toppled dictator Fulgencio Batista and took power on January 1, 1959, they closed the island's casinos. The nightclub, like almost everything in communist-led Cuba, became government property.

PAST GLORY

Cuban officials wrestled with how best to use Tropicana, but settled on using its past glory to make money in the name of promoting Cuban culture.

"This is an emblematic place for Cuba. It is one of Cuba's most important tourist products," Tourism Vice Minister Maria Elena Lopez said as she waited for the show to start.

The club's tradition of flashy shows has continued, but club director David Varela said the goal now is to showcase Cuba, not just entertain.

The price of admission is equal to about NZ$90, which is more than three times the average Cuban's monthly salary. So most of the Tropicana's customers are foreign tourists.
