I Saw Her Standing there... Best song Ever by Robert Forster des "Go Betweens"

Lennon was the only person who could say “That song is shit” to McCartney and he’d take it. McCartney was the only person who could say to Lennon “You’ve gone too far” and he’d take it. This conversation only ever takes place within The Beatles. No one later told John Lennon he’d gone too far, and no one else has ever told Paul McCartney, “That song is shit.” The legacy of this exchange is the music of The Beatles.
