Pink Floyd's Roger Waters and David Gilmour are to reunite for a one-off gig.

Following the success of the rockers' charity show collaboration in Oxford, South East England, last weekend -their first performance together since Live 8 in 2005 - the pair are to come together to perform 'Comfortably Numb' on Roger's upcoming tour of the group's iconic album 'The Wall'.

The rock duo played 'To Know Him Is To Love Him' at a special gig for the Hoping Foundation, which persuaded Gilmour to join his former bandmate for a one-off performance on his tour.

In a post on social networking site Facebook, the guitarist said: "Well! You could have knocked me down with a feather. How f***ing cool! I was blown away. How could I refuse such an offer? I couldn't, there was no way.

"Generosity trumped fear. And so explaining that I would probably be s***e, but if he didn't mind I didn't, I agreed, and the rest is history. We did it, and it was f***ing great. End of story. Or possibly the beginning."

Roger is to play a total of seven dates at London's O2 Arena and the Manchester Evening News Arena in May 2011, and the pair will decide in due course which performance David will appear at.

Roger left Pink Floyd in 1985, but the group continued without him until going their separate ways in 1994.
