Led Zeppelin have denied they are planning a world tour in 2008. The legendary rockers claim "no decision has been made" as to whether they will follow up their comeback concert at London's O2 arena on December 10 with a globetrotting series of shows. Excitement over a possible Led Zeppelin tour peaked this week after Ian Astbury, lead singer of British band The Cult, told fans at a show in Cincinnati: "We'll be back next year because we're opening for a band you might have heard of. The name starts with 'L' and has a 'Z' in it." When asked by an excited member of the crowd if he meant Led Zeppelin, Astbury reportedly nodded his head and raised a celebratory arm in the air. But an aide for the 'Stairway To Heaven' rockers insists: "No decision has been made beyond the band's performance at the O2 arena.

"Maybe Ian got mixed up and they're supporting Limp Bizkit!" Led Zeppelin have been sending out mixed messages concerning future shows. Lead singer Robert Plant has been quoted as saying "there'll be one show and that's it", whereas guitarist Jimmy Page insisted: "It's a bit selfish to do just one show. If that's it, we probably shouldn't have taken the genie out of the bottle."

The band - which also features bassist John Paul Jones - have reformed for a tribute concert for the late Atlantic Records founder Ahmet Ertegun, who signed the group.
