I believe this song is about him going through a spiritual awakening after seeing the ghost of Elvis go to the "Gates of Grace" (He's probably not talking about Graceland, but the literal Gates of Grace, three guesses were.) and he returns to the Hollywood for a dinner (Most likely) and they notice he's a musician and ask him to "do a little number" and since it was serving a Christian dinner (Because they only eat fish on Fridays during lent instead of meat)the woman playing the piano, Muriel, asks him if he's actually a Christian and he replies that he has been converted because of what he had actually recently seen, and he continues to sing, and since everyone else joins in at that point, they're all probably inspired by the story.
