Led Zeppelin fans are calling for the band to announce a world tour following the legends' triumphant comeback gig on Monday night (10Dec07). Guitarist Jimmy Page has already indicated that he would like to play more shows, but singer Robert Plant has so far appeared reluctant to commit. On the band's official website, fans urged Plant to rethink. One wrote of the show at London's O2 Centre: "If the crowd response didn't convince Robert then nothing will." Another pleaded: "Led Zep owe us a tour. Robert needs to start thinking about all the fans who love them." Twenty million people crashed the website when details of the gig were announced. A lucky 10,000 got tickets for the show - the band's first full set in 27 years. The three surviving members - Page, Plant and John Paul Jones - were joined by late drummer John Bonham's son, Jason. The charity event was held in memory of former Atlantic Records boss Ahmet Ertegun, who signed Led Zeppelin.
