In a 12/06/2011 interview with classic-rock music journalist Ray Shasho of The Examiner, Greenbaum stated that western movies were the real inspiration for “Spirit In The Sky”:
Norman Greenbaum: If you ask me what I based “Spirit In The Sky” on… What did we grow up watching? …Westerns! These mean and nasty varmints get shot and they wanted to die with their boots on. So to me that was spiritual, they wanted to die with their boots on.
Ray Shasho: So that was the trigger that got you to write the song?
Norman Greenbaum: Yes. The song itself was simple, when you’re writing a song you keep it simple of course. It wasn’t like a Christian song of praise it was just a simple song. I had to use Christianity because I had to use something. But more important it wasn’t the Jesus part, it was the spirit in the sky. Funny enough… I wanted to die with my boots on.
