"Noel Gallagher told Q magazine October 2008 that this is, "a love song inspired by the meeting of an Angel in Ibiza.""

Bass player Andy Bell told Q magazine that he thinks its about Gallagher's girlfriend and mother of his second child, Sara MacDonald. He added: "Noel can put things in a down-to-earth way that goes right to the core."

Gallagher met MacDonald at a club on Ibiza in 2000.

Given that there have been several interviews, nothing has been mentioned about any connection with any Doors song so, in my option, it's unlikely to be a tribute song.
