I have mixed feelings about very old entertainers... I hope she does it because she likes it, not because she needs to work to make a living. Her job is not as tiring as working in a factory but still, when you're 93... Look at Leonard Cohen (80) who had to tour again because he was ruined by his last divorce, he'd rather stay at home but he needs the money! Imagine Jon at 93 yo singing "WO-OH! living on a prayer!" (yes, I remember he said he would retire before he's too old to rock'n'roll but he also said that he wouldn't stop until the Stones do but Mick seems to want to perform until he turns 100!!!)
