Led Zeppelin star Robert Plant has revealed he's puzzled why bandmates Jimmy Page and John Paul Jones didn't tour without him after the group's one-night-only reunion in 2007.

Talk of a tour has been constant ever since Plant joined his pals onstage at the O2 Arena in London for a tribute to late music mogul Ahmet Ertegun, and now guitarist Page admits there were plans to hit the road with late drummer John Bonham's son Jason.

In a new Rolling Stone chat, Page says, "At the time of the O2 show we were led to believe there were going to be more (gigs). You'll have to ask Robert why he changed his mind. I don't even know if he considered it. I don't know what he thinks."

Plant has fired back by insisting his two bandmates and Jason Bonham should have recruited another singer, and toured with them, stating, "They kept rehearsing after O2 and they had a singer. I don't know what happened. It seemed like a great idea to me."

Page admits he and Jones came close to performing with a stand-in, believed to be Aerosmith's Steven Tyler, but tour plans fell apart when the bass player received a call to join Dave Grohl's Them Crooked Vultures.

He adds, "Singers were being thrown at us from here and there. The material we were coming up with was really, really good. Obviously, other people wanted to just get us out on the road quickly. I wasn't feeling comfortable. Going out with the three members from the O2 show and another singer might have looked like trying to jam a square peg into a round hole.

"(When Jones was offered the Them Crooked Vultures gig) I guess that was a pretty definitive statement."

Meanwhile, Plant insists he is glad he resisted the temptation of a Led Zeppelin reunion tour following the 2007 gig, adding, "A tour would have been an absolute menagerie of vested interests and the very essence of everything that's s**tty about about big-time stadium rock. We were surrounded by a circus of people that would have had our souls on the fire. I'm not part of a jukebox!

"I don't think there's any reason for me to do that (tour with Led Zep)... Do you know why the Eagles said they'd reunite when 'hell freezes over,' but they did it anyway and keep touring? It's not because they were paid a fortune. It's not about the money. It's because they're bored. I'm not bored."
