As she legs it into her fourth decade of pop stardom, Tina Turner is starting to show signs of fatigue. It's not that she won't be full of beans when she performs at the RDS next Tuesday, it's just that she's been around so long now, the public is starting to lose interest in the Glamorous Granny of Pop. Turner's current album, Twenty Four Seven, has been available since November 1999, but everyone's been too busy buying Whitney, Mariah and Cher albums to notice. Her last big splash in the charts was the theme from Goldeneye (written by Bono and The Edge), but the 60-year-old soul diva is sure to wallow in her back catalogue, which includes such hits as Private Dancer, We Don't Need Another Hero and Simply the Best. Support is by ex-Commodore and smoochy 1980s crooner, Lionel Richie, plus ex-Creedence and grizzly rocker, John Fogerty, who wrote one of Tina's biggest 1960s hits, Proud Mary.
