What Has Mick Jagger Never Done?

He's done everything and been everywhere, right? Wrong. Half a century in the music business and there's one thing Mick has never done. 

Mick Jagger has never performed live at the Grammys.

That will change come February 13 when he performs at the 53rd Annual Grammy Awards on CBS. He will take the stage with Raphael Saadiq during the "In Memoriam" segment to honor Solomon Burke, who died last year.

Jagger has only performed at the Grammys once before. That was via satellite with the Rolling Stones in 1986 when Eric Clapton presented the band with the Lifetime Achievement Award.

The Rolling Stones are also downplaying rumors of a 2011 concert tour. The band released a statement earlier this week that says they have "no firm plans" to tour. The statement came after claims from a former Live Nation employee that said he had a signed contract from the Stones saying they were going to tour this year. The group hasn't been on the road since 2007, but speculation is rampant that they could be gearing up for a world tour in 2012 to mark their 50th anniversary.
