Ringo Starr played drums on Harrison's All Things Must Pass and Living In The Material World, and appeared at the Concert for Bangladesh. He also played on John Lennon's solo album Plastic Ono Band. Lennon returned the favor, writing the title track of the Goodnight Vienna album, and I'm The Greatest on Ringo.
In the mid 1970's Ringo's musical career declined, with a series of albums provided diminishing returns. Harrison gave him a song for the album Stop And Smell The Roses, but Starr felt uncomfortable performing it. Harrison rewrote it and recorded it himself as All Those Years Ago, following the death of John Lennon; Starr played on it, along with Paul and Linda McCartney.
Lennon had also given Starr a song for Stop And Smell The Roses. However, he was uncomfortable recording the song in the wake of his friend's murder, and Lennon's version was eventually released posthumously on the album Milk And Honey.
Ringo played on McCartney's 1982 album Tug Of War, and in 1987 performed on George Harrison's hit single When We Was Fab. Two years later he formed Ringo Starr and His All-Starr Band, in which a number of musicians from various other acts featured. Their live shows were a success and led to a new record deal for Starr.
