The Beatles: John and Paul Feud Through Song
When the Beatles split in 1970, John Lennon and Paul McCartney began feuding in the press, but they saved the harshest words their for songs. "The freaks was right when they said you was dead," Lennon sang on 1971's "How Do You Sleep." "The only thing you did was 'Yesterday' ... The sound you make is Muzak to my ears. How do you sleep?" George Harrison played guitar on the track, so it was clear what side he was taking. Lennon and McCartney reconciled in later years, even recording together in a coke-fueled, infamously disastrous session in 1974 — but they remained distant up until Lennon's death in 1980.
