Harris recorded several albums of music, one of which, A Tramp Shining, included the seven-minute hit song "MacArthur Park" (Harris insisted on singing the lyric as "MacArthur's Park"). This song was written by Jimmy Webb, and it reached number 2 on the American Billboard Hot 100 chart. It also topped several music sales charts in Europe during the summer of 1968. "MacArthur Park" sold over one million copies and was awarded a gold disc. A second album, also consisting entirely of music composed by Webb, The Yard Went on Forever, was released in 1969. In the 1973 TV special "Burt Bacharach in Shangri-La", after singing Webb's "Didn't We", Harris tells Bacharach that since he was not a trained singer he approached songs as an actor concerned with words and emotions, acting the song with the sort of honesty the song is trying to convey. Then he proceeds to sing "If I Could Go Back", from the Lost Horizon soundtrack.
