This is Cuba: a world away from grid-locked Britain, where old, battered Cadillacs chug unbelievably along Havana's streets. Ordinary Cubans have little money, but they enjoy a support for the arts that proportionally would be considered fabulously generous here. As a result, Cuban dance, like Cuban music, enjoys a high profile abroad. They train sublime dancers who achieve international fame, such as Carlos Acosta. And yet they receive little cultural traffic in the opposite direction. Despite the focus on tourism to shore up a desperate economy, Cubans remain cut off, with little idea of what goes on elsewhere.
