Jagger composed the title song of the Stones’ 1980 album, Emotional Rescue, on an electric piano, singing in a falsetto style that was used on the eventual recording. This disco-infused track reached No.3 in America and was praised by John Lennon just days before he was murdered. “Mick Jagger has put out consistently good work for 20 years,” the Beatles star said. “And will they give him a break? Will they ever say, ‘Look at him, he’s 37 and he has a beautiful song, ‘Emotional Rescue’? I enjoyed it, a lot of people enjoyed it.” Prince was among other prominent fans of the song.
