Most of the 'older' stars are not doing anything new or interesting so why do they go on, especially as they have squillions in the bank and several houses in the choiciest places on the planet.

For the love of playing music :-) [/QUOTE]

Then why not just play local clubs. why still do massive stadium gigs, like the Stones?

put it this way, blues legends like BB King still doing the rounds..cool.
refugees from the 60s'and 70s still knocking out old rock and pop hits..very sad.
