2012 marks the 50th anniversary of The Rolling Stones—but it seems that Mick Jagger and Keith Richards won't be ringing in the semicentennial glaring at each other from separate backstage areas. According to interviews with both frontmen by Rolling Stone magazine, the Stones will likely not tour this year—mainly insiders say because of Richards' questionable health. But we may be in store for a multinight run in NYC.

Richards told the magazine the band haven't played much together since the end of the Bigger Bang tour in 2006: "Basically, we're just not ready." He added that 2013 was the new goal: "I have a feeling that's more realistic." An insider told them that Richards hasn't been the same ever since he fell out of a coconut tree in Fiji in April 2006: "They don't want to do a full tour," he says. "They don't want to travel, and there are concerns about Keith's health." More likely, the source says the band may do multinight runs at major cities: "For example, they'd do 10 nights at MSG, 10 nights at Staples, 10 nights at London's O2 arena," the source adds.

Marc Spitz, author of last year's "Jagger" biography, told us he has decided to accentuate the positive about this report:

In a way this is really good news. Even though it looks like they aren't making the anniversary in some perfect time frame (and who cares in the end if it's bang on July '62 to July '12) the question has always been 'Will they tour again at all? Or did Keith's book botch any chance of it happening?' I've been asked this dozens of times since last fall and had no answer. Only educated guesses. Now the question appears to be not 'if' but when and how, which is exciting. I always figured they had at least one more in them.

Three other interesting pieces of information from the Rolling Stone article: Jagger is moving to NYC for awhile, the band are booking studio time to start a new album for next year, and best of all, longtime bassist Bill Wyman—who left the band amicably after the Steel Wheels tour in 1992—may rejoin the band for the upcoming tour! "I think he's up for it," Richards says. "We talked about it. I'll let you know when I can."
