Paul McCartney chuckles every time a newcomer promises fans their act will be bigger than the Beatles - because there will never be another Fab Four. The British star admits he was amused when Oasis rockers Liam and Noel Gallagher boasted they'd become more famous than his group - because there's no such thing. He tells Newsweek magazine, "When they started out, Oasis... said they were going to be bigger than the Beatles. And I felt sorry for them. "It's a prediction that doesn't come true. It's a fatal prediction. I sort of sit by and go, 'Good luck, son.'"
