The Rolling Stones are only an official announcement away from officially announcing they'll be following their handful of recent 50th-anniversary shows with a full-blown tour this year.No joke: "Really, all you're going to have do is wait for an announcement," Keith Richards told Rolling Stone, reportedly with "a raspy laugh."The people who should probably be laughed at are any 1 percenters who forked over as much as $2,453.50 — or more, if they went through scalpers — thinking the recent mini-tour would be their last chance to see the Stones. Oh, sure, Mick Jagger himself suggested the tickets were so costly precisely because the Stones were only doing four shows and needed to recoup expenses that would normally be spread out over the course of a tour. But it took just a few days before the Stones added another gig, and Richards was already kindly informing consumers that yeah, the famed rockers would probably keep playing more shows."There have been quite a few offers," Jagger is quoted as telling RS now. "I'm going to see what's on the table and discuss it with everyone ... We'll announce it when we've figured it out."Or as Richards put it: "It would be dopey to bring things up to this level and say, 'Well, that's that, 50 years, bye-bye.'"With apologies to another British Invasion band, it's more like you say goodbye, and the Stones say hello. And that's good news for fans who couldn't make it to last year's concerts.
