Sir Mick Jagger thinks people will be "sick" of the Rolling Stones next year.

The 'Brown Sugar' group celebrate their 50th anniversary next year and while the 68-year-old frontman is still unsure how they will mark the occasion, he expects even fans will get tired of hearing about them in the coming months.

He said: "I don't know what form the anniversary will take.

"I am sure you will be partially sick of the Stones by the end of next year.

"We have a lot of stuff to go for. People want to do exhibitions, TV and documentaries so we have to look at those and see.

"There may be a tour who knows . maybe. At the moment nothing is fixed."

Mick thinks it is an "achievement" that the group have lasted so long and admitted he thought it was a long time 25 years ago.

He added in an interview with the Daily Mirror newspaper: "I got used to our longevity in decades.

"After 10 years I was impressed. We made a documentary after 25 years and thought that was a really long time.

"It is quite an achievement I suppose, still being around at all. I guess you should be pleased with it but, you know, I think it will be interesting to see how people react to the 50th year thing."
