After 40 Years, Iconic Album Draws a Crowd

The most influential album of all time dropped in the UK 40 years ago tomorrow, and the recording engineer who helped give the world "Sgt. Pepper's Lonely Hearts Club Band" is back in the studio putting together a tribute album—with a little help from his friends. The Telegraph follows Geoff Emerick to work.

Participants include Bryan Adams, the Stereophonics, the Killers, the Fray, and Razorlight. It's going well, with just a few snags. "The trouble seemed to be that everybody wanted to do 'Day in the Life,'" says Emerick. He's using the original four-track mixing equpiment that produced "Sgt. Pepper"—in mono, if you want to win that bar bet. (More Geoff Emerick stories.)
