Havana Night Club dance troupe flew the Habana coop
Members of Cuban Troupe Say They Will Seek Asylum

In what appears to be the largest mass defection of Cuban performers to date, 44 dancers, singers and musicians, here to stage a revue, plan to seek political asylum in the United States, troupe members said on Sunday.
. . .
The performers said they decided to stay in the United States after the Cuban authorities told them they could be jailed or at the very least not be allowed to continue as professional artists in Cuba if they persisted in their plan to work in Las Vegas.

The article states "The troupe is independent, and receives no state support." Val points out that

When you have tried to leave Cuba for the states, the Castro regime immediately takes away your job. Then, they detain you periodically and threaten to arrest you for not having thejob they took away from you in the first place.

I don't believe Oliver Stone noticed that during any of his trips to Cuba.
