Lennon recorded several albums and singles after the Beatles disbanded. The best-known one was "Imagine". He made many records with Yoko Ono. On some records they called themselves the Plastic Ono Band. Lennon and Ono worked with different musician friends, including Ringo Starr, Jim Keltner, Klaus Voormann, Harry Nilsson, Eric Clapton and Elton John. Lennon's solo music was different from his Beatles songs. He spoke more directly about his own feelings, and sometimes used harsh language or loud sounds. This upset a few fans, who wished for more Beatles music from him.
