In 1972 he went back to England to record The London Muddy Waters Sessions with Rory Gallagher, Steve Winwood, Rick Grech, and Mitch Mitchell — but their playing was not up to his standards. "These boys are top musicians, they can play with me, put the book before 'em and play it, you know," he told Guralnick. "But that ain't what I need to sell my people, it ain't the Muddy Waters sound. An' if you change my sound, then you gonna change the whole man." - Wikipedia
