Led Zeppelin might have ruled out the possibility of a reunion world tour last year, but according to the band’s lead guitarist, Jimmy Page, the touring plans are back on.

The band briefly successfully reunited for a charity concert in London in December last year, spreading hope of a possible world tour, but singer Robert Plant’s tour with U.S. country singer Alison Krauss interfered with their plans.

"The amount of work we put into O2 was what you would normally put into a world tour anyway," 64-year-old Page said of the intense rehearsing the band did for the Dec. 10 concert at London's O2 Arena.

"Robert Plant also had a parallel project running and he's really busy with that project, certainly until September, so I can't give you any news," Page, who is in Tokyo to promote a greatest hits release, added.

The three surviving members of Led Zeppelin, Jimmy Page, Robert Plant and bass guitarist John Paul Jones, joined by late drummer John Bonham’s son Jason on drums, got together for the first time in 19 years for a tribute show for Atlantic Records founder Ahmet Ertegun, who died last year.

"It was exhilarating, fantastic, every week was a week to look forward to," Page said. "We did the show and it was great."

The band played some of their classics, from "Stairway to Heaven" to "Whole Lotta Love," and "The Song Remains the Same," in front of 20,000 fans.

"That is what was so thrilling really, to come together after all this time and find that there was so much chemistry and so much electricity involved in these four characters."

Chris Goodman, from The Outside Organisation, who look after the band’s PR, said: "Jimmy has said that the band will be meeting up in August to talk about it.  "The band meet all the time. There is something in it but I can’t give you any more news at the moment."
