Led Zep are planning a two hour music fest at their comeback gig at the O2 Arena on December 10th. Originally they were approached to play for 40 minute, which would have been a rip off for fans. However, as time moved on, they increased the set length to 75 minutes, then to 90 minutes, and now to almost a full two hours. Jimmy Page explained in Q magazine: "If we go out and play 'No Quarter', 'Moby Dick' and 'Dazed And Confused' with all the solos, you're already talking over an hour."
Anything more than two hours would be a bit much for the ageing rock gods, but at least the fans will get something worthwhile for the over inflated ticket prices (which perhaps would've been worth it if the late Bonham senior was on the throne).
