Possession” is a song by Canadian singer-songwriter Sarah McLachlan, and was the first single from her album Fumbling Towards Ecstasy. It was written and composed by McLachlan herself and was produced by Pierre Marchand. It was released in Canada on 10 September 1993 by Nettwerk Records. The song appears twice on the album, as the first track and as a hidden track at the end, which is a solo piano version. “Possession” is written from the viewpoint of a man obsessed with a woman, and was inspired by consistent fan letters to McLachlan some time before the writing of the song from computer programmer Uwe Vandrei, who sued McLachlan for using his words without crediting him. However, Vandrei committed suicide before the case could ever be taken to court.[1]
