They're back!

After their sensational comeback at London's O2 arena on Monday night, rumours are now rife Led Zeppelin are set to embark on a world tour, which could net them a massive £1 billion. All ticket sellers have been told a world tour will take place, there's just some ironing out of contracts to be done. They are already talking about playing venues like Knebworth and Glastonbury. They were looking to do it in March but now it will most likely be May. The band were really fired up and were talking about their late drummer John Bonham and what he would have thought about it - it was time for reflection. Earlier this week, Plant fuelled tour speculation, saying: "It wouldn't be such a bad idea for Led Zeppelin to play together from time to time." Page has previously stated: "It's a bit selfish to do just one show. If that's it, we probably shouldn't have taken the genie out of the bottle." If the tour does go ahead drummer Jason Bonham, who replaced his late father John Bonham for the reunion, is expected to join the original trio.
