Turn out all the lights and call on the Lord
A man I knew, born in 1921, used to enter a room at festive gatherings and say "Turn out all the lights and call on the Lord." Do you know the origin of that phrase, or do you think it was just an idiosyncrasy of his?
Turn out all the lights and call on the Lord appears to be as you said, idiosyncratic. His own 'turn of words'. I can find no registry listing for the same, nor anything close. I suspect his intention was meant 'to focus on said deity'!
