In an interview with Sue Lawley in 1992, Clapton said of the song, "There is a song that I’ve written for a movie, but in actual fact it was in the back of my head but it didn’t really have a reason for being until I was scoring this movie which I did a little while ago and then it sort of had a reason to be. And it is a little ambiguous because it could be taken to be about Conor but it also is meant to be part of the film."
