Paul McCartney – Secret Guests in Rock Songs

Paul McCartney got the much-needed chance to blow off some steam -- and Steve Miller got a killer rhythm section -- when the two spontaneously collaborated on Miller's 'My Dark Hour' single in May of 1969.

As McCartney explains the story, the rest of the Beatles had left him alone in the studio following a nasty argument. "Steve Miller happened to be around: ‘Hi, how you doing? Is the studio free?’ I said: ‘Well, it looks like it is now, mate.’ He said: ‘Mind if I use it?’ So I ended up drumming (and reportedly, playing bass) on a track of his that night…. I had to do something, thrash something, to get it out of my system.”
