Fans urge Led Zeppelin to tour after success of one-off concert

They came, they rocked and they conquered. The long-awaited comeback concert by Led Zeppelin has left fans clamouring for more.

Following Monday's sell-out performance at the O2 Arena in Greenwich, south-east London, a vociferous campaign for a permanent reunion of the band has begun. And there is only one discussion topic among lovers of heavy rock whether reports of a Led Zep reunion tour are true.

Jimmy Page, the guitarist, has already hinted that he might be interested in performing again. But the singer, Robert Plant, who before the gig had played down the band's chances of meeting fans' expectations, has been silent on the issue.

On Monday, Plant, Page and bandmate John Paul Jones played at a tribute concert for the Atlantic Records founder Ahmet Ertegun alongside Jason Bonham, the son of their original drummer John Bonham who choked to death in 1980. The trio are now deciding whether to arrange further gigs, and an announcement could come as early as this week.

Speculation has been mounting since The Cult let slip that next year they would be supporting a band with an "L" and a "Z" in their name. According to the music magazine NME, "live industry sources" have confirmed that two Led Zeppelin dates are provisionally booked at Wembley Stadium next summer. A spokesperson for the band said: "It is just speculation at this stage. They were always going to see how the gig went. Now the dust has settled, we'll see."

Fans contributing to the group's official website are already begging for a tour. In an open letter yesterday, one wrote: "Led Zeppelin have just proved that, after 28 years, they are still the greatest rock band of all time. So now we come to the shameless begging. Please, Robert, please. If 20 million people vying for 18,000 tickets doesn't change your priorities, then I suppose nothing ever will."

Another fan told the trio whose combined age is 183 to seize the moment. He added: "When you are in your sixties and are lucky to have survived your thirties, time isn't on your side. They haven't been this close in 20 years it's now or never.

"The day one of these guys doesn't wake up in the morning is too late to wish they had done more." The success of the concert also hit home for the reported 20 million people who tried and failed to obtain tickets through an online ballot. "I hope they will reunite," said one plaintive fan. "There are so many of us who missed out on a concert we had imagined for nearly three decades."
