The Rolling Stones live tour announcement has caused an Internet pileup, as over a million fans log on to online ticket vendor Viagogo to find out about tickets, Gigwise reports.

It seems as though the incredibly high-ticket prices won’t put off fans of the ageing rockers, but with a place at one of their London or New York concerts so highly coveted, there could be plenty of illegal activity surrounding ticketing. "The Rolling Stones are a global phenomenon – and one of the last supergroups still performing with a full line up," says Viagogo spokesperson Ed Parkinson. "This is a once in a lifetime opportunity to see them, and there will be some unscrupulous organisations looking to take advantage of that. Always check the reputable ticket market places like Viagogo to find the true market value and never buy a ticket that isn’t 100% guaranteed."

Another musical event often shrouded in ticket controversy is British festival, Glastonbury, and Keith Richards has started the rumour mill about a possible appearance. "On a good day, if the weather's fine, [Glastonbury] is an interesting proposition," he told the BBC, before hinting at future Rolling Stones live shows, adding: "Anything is possible. This band isn't going to wind up with four shows."
