Since they were introduced to the world via the evangelism of American musician Ry Cooder, the Buena Vista Social Club have been Cuba's most successful export since those cigars beloved of Bond villains.

The undoubted star of the evening was diva and birthday girl Omara Portuondo.
Her duet with husband Papi Oviedo including a cha cha cha that put everyone in Strictly to shame was the highlight of the evening, as was her version of Perhaps, Perhaps, Perhaps.
No wonder they unrolled the Cuban flag in el pito del mosho.
