Former Rolling Stones bassist Bill Wyman, 75, stood arm in arm with his old pals Mick Jagger, 69, Keith Richards, 68, and Charlie Watts, 71, last night at the premiere of a documentary celebrating the band's 50th anniversary.

Wyman split from the band in 1990. But wearing a blue blazer and sunglasses, he still looked pretty rock 'n' roll.

But sadly he won't be joining his bandmates for their O2 gigs next month.

Speaking from the red carpet at the world premiere of Crossfire Hurricane the Stones fuelled rumours that they will play at Glastonbury next year.

Richards said: "I don't know yet...I'd love to though."
