Led Zeppelin have promised fans an epic two-hour set at their comeback concert.
Guitarist Jimmy Page insists the legendary group plan to play a multitude of hits from their impressive back catalogue, at London's O2 arena on December 10, and scoffed when it was suggested they could only perform for 40 minutes.
He told NME magazine: "We couldn't just play for 40 minutes.
"When we were first asked to do this we were asked to do a 40-minute set. We soon realised we couldn't.
"If we go out and play songs like 'No Quarter', 'Moby Dick' and 'Dazed and Confused', with all the solos, you're already talking over an hour.
"There's no way I can take on playing three-and-a-half-hour sets now, like we used to. I just don't have the energy for that any more.
"But I've still go enough in me to get through a two-hour set."
Earlier this week, Page revealed he is considering asking Sir Elton John for tips on performing at The O2 arena.
He said: "A lot of acts seem to be struggling with the sound there. The Rolling Stones sounded terrible. Prince wasn't great and Snow Patrol was this great monolithic noise.
"The only guy who sounded good was Elton John so I may speak to his sound man."
The band - which also comprises of lead singer Robert Plant and bassist John Paul Jones - have reformed for a tribute concert for the late Atlantic Records founder Ahmet Ertegun, who signed the group in 1968.
