Clapton played again with John Lennon and his new wife Yoko Ono, as a member of the Plastic Ono Band. He appeared with them onstage in Toronto that September, and played guitar on "Cold Turkey", Lennon's song about heroin addiction. At that time, the Beatles were getting ready to break up. Lennon thought about asking Clapton to join his and Ono's new band, but decided not to have a permanent lineup.
