. The song was one of the last songs that was recorded for the album, and it is, in fact, a homage to a priest that lived near the studio where Born Again was recorded. The priest that went in the studio to ask them to play it low.

Gillan also explained the genesis of "Disturbing the Priest":

We were in loud playback mode, with the door open...When the track ended I was surprised to see a nervous vicar standing in the doorway. He explained how wonderful he thought the music was, but they were having choir practise in the adjacent village church and so would we mind closing the door…? I apologised immediately, we got hold of his schedule and never worked again during those times. The following evening I had a few beers with the vicar and signed some autographs for the choir. It was Geezer who came up with the title as we were laughing about the story some days later.
