The Rolling Stones are already planning their 60th anniversary tour.

The band - made up of Sir Mick Jagger, Keith Richards, Ronnie Wood and Charlie Watts - are currently busy on their '50 and Counting' world tour but have made time to discuss what they'll do to mark the milestone anniversary.

Speaking to Class Rock magazine, guitarist Keith said: ''I've been hooked on everything once or twice in my life. The one thing I can't kick is playing with the Rolling Stones

''All these zeros that keep zooming by...30, 40, 50 years. I don't really see any reason why there shouldn't be a 60th. Either that or we croak on the job''

The group- who are currently headlining at the Glastonbury festival this year - admit they've had to overcome wavering relationships between the band members, particularly between Keith and Mick.

Keith explained: ''What do you expect after 50 years?''

''You've got two very volatile guys who've been through a whole lot of stuff in their lives, and still somehow, when we look at each other, manage to say, you know what's what and I know what's what, let's get on with it

''Sometimes I despise the man, other times I love that man so much. It's like your brother. I never had one, so he is my brother, bless his heart.''
