[STORY UPDATED] Something rather unexpected happened last night: in a bolt out of the blue, David Gilmour and Roger Waters performed together for the Hoping Foundation Benefit Evening! Guy Pratt performed bass duties whilst Roger was on acoustic guitar, with Roger playing bass at other points during the evening's performance. For those of you surprised by Guy's inclusion, some of you will recall from our Guy Pratt interview back in 2005, Guy was asked to play bass for Pink Floyd at Live8 when the reunion happened... We now know that the show took place - not in London, as noted by Getty Images - but at the rather splendid Kiddington Hall, in Oxfordshire. News of the show, and the appearance by David and Roger, was broken by one of the hosts of the evening, TV presenter Fearne Cotton, who tweeted about the event in the early hours of this morning. There's a number of pictures from the performance, and the evening itself, over at Getty Images, and if you click the thumbnail to the right, you'll go directly to them. This evening, more details emerged courtesy of David's blog - the tracks performed were: To Know Him Is To Love Him, Wish You Were Here, Comfortably Numb, and Another Brick in the Wall (Part 2)... The band consisted of David, Roger, Guy Pratt (bass and acoustic guitar), Harry Waters (keyboards), Andy Newmark (drums), Chester Kamen (guitar) and Jonjo Grisdale (keyboards). Quite a line-up, who performed in front of 200 very lucky people, raising some £350,000 for the Hoping Foundation (Hope and Optimism for Palestinians In the Next Generation) in the process.
