This can be classed as a weepie.
Perhaps Love is a song written by John Denver and recorded as a duet with Placido Domingo, the Spanish Tenor in 1981.
It was addressed to his wife while separated and moving towards a divorce. After John's death in 1997 in a plane crash, his wife, Annie, said this was her most favourite song of his.
