What was the name of John Lennon's band after The Beatles breakup?

John Lennon’s band after the Beatles breakup was the Plastic Ono Band. Formed by Lennon and Yoko Ono in 1968–69, it was both a rock group and an experimental artistic collective used for recordings, live performances, films, and conceptual projects.

The group did not have one permanent lineup. Its musicians varied by project, but members and collaborators included Eric Clapton, Klaus Voormann, Alan White, Ringo Starr, Billy Preston, Jim Keltner, and Lennon’s former Beatles bandmates George Harrison and Ringo Starr. Lennon’s first performance with the group was at the Toronto Rock and Roll Revival festival in September 1969.

After the Beatles publicly broke up in 1970, Lennon recorded John Lennon/Plastic Ono Band, released on 11 December that year alongside Yoko Ono’s similarly titled album. The record’s stripped-down sound and intensely personal songs marked a sharp change from the Beatles’ studio productions. The Dirty Mac was a one-off supergroup, while Wings belonged to Paul McCartney, making both common but incorrect alternatives.
