He was the Beatle who caused a firestorm when he said the group was "bigger than Jesus." He insisted that Yoko Ono sit alongside him in the recording studio, even when a car accident forced her to bring in a bed. They later posed naked together on an album cover. He fought the Vietnam War to the point that the Nixon administration actually tried to deport him. He then totally walked away from his music career for five years to raise his newborn son. John Lennon could have played by the rules in the 1970s by releasing regular albums and launching big-money tours where he played old Beatle hits, but he had absolutely no interest in doing that. He played by his own rules until the very, very end.
