“Perhaps Love” is a song that John Denver wrote and recorded as a duet with Plácido Domingo. The song appeared on Domingo’s 1981 album of the same title. “Perhaps Love” is the only song on the album with Denver’s vocals alongside Domingo’s. Denver also appears on the album’s cover version of his composition “Annie’s Song”, where he accompanies Domingo on guitar. Released as a single with “Annie’s Song” on the B side, “Perhaps Love” peaked at #22 on the U.S. Adult Contemporary chart and #59 on the Billboard Hot 100 in 1982.  Remaining in print, the song sold almost four million copies by 2008.

“Perhaps Love” was addressed to Denver’s wife Annie Martell (the eponym of his #1 hit “Annie’s Song“) while they were separated and moving towards a divorce. In an interview the day after Denver’s death in 1997, Annie said that this was her favorite song of his, rather than “Annie’s Song” (which she also said she enjoyed).
