Gilmour pays tribute to his deceased friend.

Richard Wright, keyboard player and founder member of Pink Floyd, has died aged 65.
The musician, who sang and wrote material on the albums Dark Side of the Moon and Wish You Were Here, lost his battle with cancer last night (September 15th).
His death was confirmed by his family, who have asked for their privacy to be respected during this difficult time.
Paying tribute to Wright, band member Dave Gilmour said his contribution was often overlooked and claimed he is irreplaceable.
"No-one can replace Richard Wright - he was my musical partner and my friend. In the welter of arguments about who or what was Pink Floyd, Rick's enormous input was frequently forgotten," he said.
Wright met fellow members Roger Waters and Nick Mason in college and formed the band in 1965.
In 2005, he was part of the group's first reunion in 25 years when they performed at the Live 8 concert.
Meanwhile, Gilmour recently told the Associated Press he would not become involved in another Pink Floyd comeback.
