Led Zeppelin are reuniting for one night only.The legendary rock band - who split 27 years ago following the death of drummer John Bonham - will perform at London's O2 arena for a special tribute concert on November 26.The remaining Zeppelin members, singer Robert Plant, guitarist Jimmy Page and bassist John Paul Jones, will be joined on drums by Bonham's son Jason for the charity event held in memory of the late Ahmet Ertegun, the founder of Atlantic Records, who died last year.Speaking at a press conference yesterday, Plant said: "During the Zeppelin years, Ahmet Ertegun was a major foundation of solidarity and accord. For us, he was Atlantic Records and remained a close friend and conspirator. This performance stands alone as our tribute to the work and the life of our long standing friend."The Who guitarist Pete Townshend, former Rolling Stone Bill Wyman and his band the Rhythm Kings, Foreigner and Paolo Nutini, who were all mentored by Ahmet, will also perform.In an effort to beat ticket touts, fans must register at website www.ahmettribute.com, which automatically enters them into a ballot for tickets, which will cost £125 each (U.S. $250.) .Names will be picked at random, but tickets will be limited to two successful applicants per household.Profits from the O2 show will go to the Ahmet Ertegun Education Fund, which pays for student scholarships to universities in the UK, US and Turkey.The concert - which coincides with the release of a new Led Zeppelin greatest hits collection in November - will be the first time the band have performed together since 1995, when they played at their induction into the Rock And Roll Hall Of Fame. They also reformed for the 1985 Live Aid concert in Philadelphia.
