The latest rumors surrounding Led Zeppelin's possible return to the road have Alter Bridge singer Myles Kennedy performing with Jimmy Page, John Paul Jones and Jason Bonham. Billboard reports that Kennedy has rehearsed with the band multiple times. Billboard also reports that if Kennedy splits with Alter Bridge for Zeppelin, the other members of Alter Bridge would be free to participate in a potential Creed reunion. Meanwhile, Chris Cornell addressed rumors that he would be involved. "I have not been approached so far to fill in for Robert Plant on the upcoming Zeppelin tour, but that isn't to say I won't be," Cornell told MTV News. "I've heard that from about 200 people now, and it might be one of those situations where it's just an online rumor or it might be true. But if you see anyone from Led Zeppelin around, let me know. I think I should actually fill in for Jimmy Page on the Robert Plant/Alison Krauss tour."
