Keith Richards, 1972.

Time has treated the band favorably; this year, they're celebrating the 50th anniversary of their marriage to sex, drugs and rock 'n' roll. 

Though fans across the globe are crying for a tour in celebration of the milestone, they'll have to wait at least another year for those plans to materialize. 

According to a story published in the March 29th edition of Rolling Stone magazine, the band is not going to hit the road until 2013.

The article suggested the health of guitarist Keith Richards to be a primary cause of the delay. The legendary bluesman, who turned 68 in December, most recently appeared at a tribute concert to Hubert Sumlin in February, though he hasn't been on a full-fledged tour since 2007. 

Due to the age of the band members and the stresses of travel, it's possible that the Stones will perform multiple shows in select cities, similar to what Prince did last year.

"For example, they'd do 10 nights at MSG, 10 nights at Staples, 10 nights at London's O2 arena," an undisclosed industry source told the magazine. 

Earlier this week, the band announced the development of a documentary chronicling their 50-year history:

"The film is a cinematic journey through the incredible eye of director Brett Morgen, capturing hours of never-before-seen footage in a rare, uncensored format that reveals the band’s vivid stories told through their eyes and their voices."

In an interview for the film, Richards finally cleared the air about the controversial comments in his 2010 memoir "Life" which attacked frontman Mick Jagger. 

"As far as the book goes, it was my story and it was very raw, as I meant it to be, but I know that some parts of it and some of the publicity really offended Mick and I regret that."

The documentary, which is slated for a September release, will be distributed by Eagle Rock Entertainment.
