look at this from the Guardian UK, right hand side, halfway down. i dont think it's right, more likely an automatically generated thing to accompany the article, but wow, it got my blood pumping for a sec! guardian
I don't believe it one bit, but it is interesting. There are 0 tickets available of course and we can only speculate (as always) why is it there, but I think that none of us believes that any tour news would leak that way. It would be lovely news though.
These things have been springing up for a few months in various media outlets. I doubt wether there is anything serious in it. I did think maybe the Stones themselves do it to gauge responses to it and give them a way of working out whether it's worth putting on a gig in those cities?
Great news. Might not be the date, but it makes a tour sound more concrete. Months before the Bridges to Babylon tour was announced, there was a date on ticketmaster's website for "Mick and Keith", then it disappeared.
