Disguised as Phil Collins

Radiohead attempted to disguise their secret recording sessions by disguising their masters, explains Colin Greenwood:

"It felt like a gigantic risk. Like Mission Impossible, almost. We destroyed all CDs after every day of recording.

"And on the master we'd always write a name which probably nobody would listen to if we had lost it; Eagles: Greatest Hits, Kula Shaker demos, Phil Collins hip-hop covers."

Which explains why you should double-check that copy of the Eagles Best Of you bought for your Dad down the pub before you give it to him on Christmas Day.
