Colin and Joanne Petersen continued to manage Jonathan Kelly as a solo artist through to his third LP release,"Til They Change The Backdrop" (1973), but Colin had no musical involvement in Kelly's solo albums. Kelly became unhappy with attempts to market him as a pop star and tired of the "totally ruthless and callous" music industry. He parted company with the Petersens in 1974, recorded two further albums, found religion, and retired from performing for many, many years. In 1991, Jonathan Kelly performed at a Bee Gees tribute concert and formed a cover band for the occasion which included his son Greg on lead guitar, Jonathan played drums.
