Keith Richards told Rolling Stone magazine that the band just isn’t ready to hit the road. But it looks like we’ll see a tour from the group in 2013. Besides, Keith says "The Stones always really considered '63 to be 50 years, because Charlie [Watts] didn't actually join until January," Richards says. "We look upon 2012 as sort of the year of conception, but the birth is next year.”

Rolling Stone sites sources pointing a finger at Keith’s health as a reason for the delay. Residual effects from the Stones guitarist’s head injury while on vacation in Fiji in 2006 are believed to have taken a toll on his performances on the Bigger Bang tour that year. After the tour, Richards put the guitar down completely. As late as 2010 Keith told Jimmy Fallon "You are looking at a very rusty Keith Richards right now…"

One concert business insider told the magazine “…there are concerns about Keith's health." To mitigate the rigors of a world tour the band may limit their traveling by setting up residencies in larger cities. "For example, they'd do 10 nights at MSG, 10 nights at Staples, 10 nights at London's O2 arena," the source says.

In the meantime Keith is working on a solo album and he says the Stones have some studio sessions planned as well. And while we wait for a 2013 tour we can entertain ourselves this fall with a new Stones documentary that Keith says features mostly never before seen footage of the band spanning their entire 50 year career.  Read more.
