Phil Manzanera on being sampled by Kanye West and Jay-Z: "Who knew that I would earn more money from a short guitar riff that I wrote one evening on a sofa in front of the telly in 1978 than I ever earned in the entire 50 years as a member of Roxy Music?"

Roxy Music guitarist Phil Manzanera's new book Revolución To Roxy has revealed how the guitarist discovered a riff from his 1976 solo album K-Scope had been sampled on the opening track to Kanye West and Jay-Z's 2011 album Watch The Throne.

Fielding a call from a representative of Roc-A-Fella Records in New York one day, Manzanera at first thought they'd been a mixup when he was informed that the artists had sampled his riff for an album due to be released the following week.
