Sir Paul McCartney misses his time with THE Beatles, because he was at his most creative when he was one of the Fab Four.

The singer now makes music on his own and he admits he misses the creative input of equals - as well as the camaraderie that comes with a band.

He says, "I miss company. I miss having a bunch of people around to tell jokes to and to hear jokes from. You do get a little bit like an absent-minded professor on your own.

"It's actually not a bad thing, but it's more marked when you're in the studio yourself, without a producer. You get stir crazy."
