Following drummer John Bonham's death in 1980, the remaining members of Led Zeppelin reunited for 1985's Live Aid charity concert - where they were joined by drummer Phil Collins and Tony Thompson - and Atlantic Records 40th Anniversary event in 1988 with Bonham's son, Jason, behind the kit.

The group reconvened for a one-off performance at the December 10, 2007 concert at London's O2 Arena tribute concert for friend and Atlantic Records founder Ahmet Ertegun. The rare live set was released in 2012 as "Celebration Day."

"We tried it a few times," Page tells The Daily Beast. "It always seemed to be done in a hurry and it never worked. That's why the O2 show was done with such intent. We rehearsed loads so that Jason - John's son - felt like he was part of the band and not just some novelty. We all needed it to be that way. But I can't foresee doing it again, because we all have to agree and agree for the right reasons."

"It was a blend of these four master musicians, and each of us were important to the sum total of what the band was," hee adds. "I like to think that if it had been me that wasn't there, the others would have made the same decision not to carry on. Besides, we couldn't just get somebody in there and say, 'Do this, this way?' That wouldn't have been honest or of the same creative nature that we had always striven for. And it's why we still have only done it properly once."

A UK tabloid report last year claimed Robert Plant had allegedly turned down an $800 million (�500 million) offer from Virgin head Sir Richard Branson for a Led Zeppelin reunion tour.
