The album cover to Greenbaum's hit song. On his Twitter page, Greenbaum describes himself as a "one-hit wonder."

A photo of Greenbaum circa 1970. "Because of 'Spirit in the Sky,' I don't have to work. So in that sense, it's a comfortable living," Greenbaum told The New York Times in 2006. He said he wrote the words in 15 minutes.

With its distinctive fuzz-toned guitar, spacey effects and gospel-tinged harmonies, "Spirit in the Sky" has been featured in more than 40 movies and TV shows, including "Remember the Titans," seen here.

Celebrities such as Elton John have performed covers of "Spirit in the Sky."
