According to Telegraph, LED ZEPPELIN frontman Robert Plant has ruled out the band getting back together for a concert tour. Plant, 60, said he has moved on to other things and was getting too old for two-hour rock shows in giant arenas across the world.Plant was on stage yesterday being interviewed on BBC Radio Wales by actress Ruth Jones who plays Nessa in TV's "Gavin and Stacey". Plant is expected to enter the studio in January with American bluegrass singer Alison Krauss to begin work on the follow-up to their award-winning "Raising Sand" LP. He said: "I'm doing very well with Alison and I'm enjoying that. "I still see Jimmy [Page, guitar] quite a lot and he's very complimentary and supportive of what I'm doing. "But we are in different places now and you have to go on to do different things." When Ruth asked him about a ZEPPELIN reunion, Plant said: "Do you know how long it took me to climb up onto the stage here — and it's only four steps!"
