Sir Paul McCartney was terrified of making a greatest hits album - because he didn't think his solo efforts were good enough. The Beatles star admits he "dreaded" the prospect of a compilation of his work after the group disbanded in 1970, but was pleasantly surprised by the end result, The MCCartney Years. He says, "I thought, 'Oh no God, there's not enough good stuff yet.' "But looking at it, I think some of the stuff I was a bit scared of, I don't need to be scared of. Especially as it's all been re-polished and buffed up. They seem to stand up quite well."
