Led Zeppelin rumors heat up again

Rumors about a Led Zeppelin reunion have resurfaced again, thanks to the news that singer Robert Plant has been in discussions about performing at next year's Glastonbury Festival in England. According to NME.com, however, what sparked speculation about a Zeppelin gig was when Plant remarked, "There's a place for me there (at Glastonbury), but I have no idea who with."

The surviving members of Led Zeppelin -- Plant, guitarist Jimmy Page and bassist John Paul Jones -- reunited in December 2007, along with late drummer John Bonham's son Jason behind the kit, for a benefit concert in London.

The performance fueled global rumors about a tour, but Plant repeatedly denied interest. He said about the London show itself, "The endless paperwork was like nothing I've experienced before. I've kept every one of the emails that were exchanged before the concert and I'm thinking of compiling them for a book."

Page, Jones and Bonham did rehearse together and mulled the idea of touring with another frontman under a different name. Although names such as Steven Tyler and Chris Cornell were mentioned, only Alter Bridge vocalist Myles Kennedy was confirmed to have rehearsed with the trio.

Jones, who is now playing in Them Crooked Vultures with Dave Grohl and Josh Homme, told BBC News this week, "Jimmy and I rehearsed a bit with Jason Bonham and we couldn't really agree on singers and that fell by the wayside. Then this came along and to be honest, I'm really happy."
