The 1997 Buena Vista Social Club album gave some veteran Cuban musicians a new lease of life: Ibrahim Ferrer, a great star in the 1940s, had fallen on hard times and was shining shoes in Havana to earn extra cash, while pianist Ruben Gonzalez, who helped pioneer the cha-cha and the mambo dances, had retired after struggling with arthritis, his piano riddled with termites, when they were called up to join the group.

But with so many of the stars in their twilight years when the band began－death and illness has taken its toll on membership over the past 20 years. Portuondo is one of a few from the original line-up to remain, and just this month Jesus 'Aguaje' Ramos pulled out of the Hong Kong performance for health reasons. The injection of young talent means the ensemble now performs under the name Orquesta Buena Vista Social Club.

The Adios! Tour pays homage to the band's history combining new talent with the veterans, as well as images and footage of elder statesmen of Cuban music now passed.

"They have always been part of us and of the music," says Portuondo.

For the diva, who began performing 70 years ago at Havana's famed Tropicana club, the Buena Vista chapter is just one high note in a remarkable career that has seen her work with stars such as Nat King Cole, Herbie Hancock, Edith Piaf, and Chico Buarque. And the octogenarian expects plenty more.

She says: "Is this goodbye from me? Never! Next I'll be touring in Europe and USA with my '85 tour' to celebrate my life and career."
