The band played Wembley Stadium for Live Earth in 2007
Spoof band Spinal Tap have announced a "world tour" consisting of a single June date at London's Wembley Arena.
The tour marks the 25th anniversary of mockumentary film, This is Spinal Tap, which launched the band's career.
The band will be backed by 1960s folk trio The Folksmen, the focus of another spoof film, 2003's A Mighty Wind.
Spinal Tap's lead guitarist Nigel Tufnel commented: "If we're going to do a World tour on only one night, at least it's this world."
Bassist Derek Smalls added: "one night is not enough, and it's way too much".
Spinal Tap have used a variety of drummers over the years due several untimely deaths, including a spontaneous combustion on stage.
The rest of the line-up for the world tour has not been announced but the group paid tribute to former members.
Singer and rhythm guitarist David St Hubbins said: "This show will be dedicated to all of our drummers who have passed on, either to their reward or to middle management at Sainsbury's."
The band also announced that they had tried in vain to produce some new material and will instead be releasing a new lost album this summer.
Their last tour was the Back from the Dead series of gigs in the US and Canada in 2000 and in 2007 they appeared at Live Earth.
Bassists from almost every other act on the bill including Metallica, Foo Fighters and Beastie Boys, joined Spinal Tap on stage in an effort to get the noise level up to 11 - a comedy reference to the film.
The announcement of the new tour comes after the band revealed on their website that their Unstoppable tour, scheduled for this year, had been cancelled.
The men behind Spinal Tap will be touring in their own right this summer
A letter from the tour promoter explained: "The poor economy plays a role in this decision, as does the band's history, pertaining to shows."
Spinal Tap are played by Harry Shearer, Christopher Guest and Michael McKean. The three actors will be touring America this summer in their own personae for a series of acoustic gigs called Unwigged and Unplugged.
Tickets for the one off Spinal Tap London gig go on-sale on 9th April at 0900.
