"Jean" was also recorded by the American singer Oliver. Earlier in 1969, Oliver had reached #3 on the Billboardpop and easy listening charts with his version of "Good Morning Starshine," a song from the musicalHair. While working on an album with producer Bob Crewe (which would also be called Good Morning Starshine), "Jean" was selected as a song for the record and subsequently chosen as the follow-up single. It became another hit for the singer, reaching #2 on the pop chart and spending four weeks at #1 on the adult contemporary chart. Oliver would later describe his cover version of the song: "We had no idea it would be a single. It was a 3/4 ballad in the psychedelic era...it was a beautiful arrangement."
