Plastic Ono Band
The second version of the Plastic Ono Band included Ono and Lennon in person, along with musicians Eric Clapton, Klaus Voormann and Alan White. They performed together at a rock concert in Toronto in September 1969, and it was the first time Lennon had played in public with a band other than the Beatles. The show went well, and helped Lennon decide to leave the Beatles, which he had thought about doing for some time. A second single, "Cold Turkey", was recorded with this lineup.
