It's one of the crazier rumors we've ever heard here in the MTV News offices (and we hear crazy rumors all the time) and, so far, it's been impossible to confirm or disprove, because no one involved is talking — not on the record, at least.

It involves Led Zeppelin — who returned to the live stage last December, for a single performance in London — launching a full-scale reunion tour, which means it probably isn't true at all, given what frontman Robert Plant recently said.

"It's both frustrating and ridiculous for this story to continue to rear its head when all the musicians that surround the story are keen to get on with their individual projects and move forward," Plant told the U.K. press, following the publishing of an article intimating that Foo Fighters frontman Dave Grohl, ex-Soundgarden singer Chris Cornell and Van Halen's erstwhile frontman Sammy Hagar could replace him on a Zeppelin reunion run. "I wish Jimmy Page, John Paul Jones and Jason Bonham nothing but success with any future projects."
