Roger Waters joined by Dave Gilmour

Pink Floyd singer Roger Waters was joined onstage by former band mate Dave Gilmour last night (May 12th).

Pink Floyd have a fractious recent history. One of the biggest band's on the planet, the English group dissolved into a series of court cases throughout the 80s. Roger Waters left the band, and attempted to claim the name Pink Floyd.

His band mates won, although Roger Waters was granted the copyright to 'The Wall'. Since then, Pink Floyd have rarely re-united with the most high profile exception being an awkward performance at Live8.

The show was televised, with an audience of millions seeing the quartet's obvious discomfort at being onstage together. However the show seems to have mended some bridges in the Pink Floyd camp, leading to last night's re-union.

Roger Waters is on the European leg of his 'The Wall' tour - inspired by the classic Pink Floyd album. Fresh from the news that the band are to embark on an enormous re-issue project, spirits were clearly high.

Reaching the anthemic track 'Comfortably Numb' the spotlight shone on a guest star - none other than Dave Gilmour. The guitarist belted out his classic solo, to the clear delight of both fans and Roger Waters.

The emotional moment marked a rare re-conciliation between the pair. However it is not without precedent: last year Roger Waters and Dave Gilmour played a short set for charity before arranging on Facebook to do something similar on 'The Wall' tour.

Taking place in the O2 Arena, the show was part of Roger Waters' epic tour for 'The Wall'. Speaking earlier this year, the songwriter insisted that fans should enjoy the shows while they can.

"Constructing something like this indoors - I'll probably never do anything this big again, the technology of projection we've used in this show is breathtaking," he said.

'The Wall' is now set to move on to Manchester's MEN Arena.
