John Lennon might have been the first Beatle to mentally check out of the band. As he fell into a deep depression in the mid-1960s that he compared to going through murder, Paul McCartney became the de facto leader of the band. By then, the whole group had committed to not playing live, though John performed one more concert without his bandmates before leaving the group. Still, John lost a bet to Elton John and made one more proper, final concert appearance in the mid-1970s.

John Lennon lost a bet with Elton John that led to his final major concert appearance

John all but stopped playing live when The Beatles stopped touring. Elton John single-handedly got the ex-Beatle back on stage in 1974, and it was the final time John Lennon played original songs in front of a massive concert crowd.
