Paul McCartney has said that his collaborations with John Lennon worked so well that it spoiled him for working with anyone else. The former Beatle told 6Music: "I'm a little bit wary of collaborating with other people because it doesn't happen as easily or as amazingly as it did with John".
He continued: "It's a funny subject the collaboration thing because I collaborated with John and you're a little bit spoiled after that. That was one hell of a collaboration. I've done it quite a bit since and, I think - and I hate to say it - there's inevitably a sense of disappointment because it was just so cool for John and me to be working together, because we started so young and knew each other's ways and minds."
