Okay, alternative nativity:
Opens with the usual "Caesar decreed that a census be taken of the known world..."
Set of a inn. There's a bar, few tables, door with a sign saying "rooms", a reception desk. The place is heaving. The innkeeper and his wife are getting more and more stressed out. More and more people keep arriving.
People insisting that they made reservations, that the room is too hot/too cold, where's the meal they ordered, the wine tastes like there's a rat in it. It all gets louder and louder. Lots of people desperate that they don't have a room, and they've got kids, sick mothers, disabled grandads. Roman soldiers turn up to say they're all making too much noise, and they don't want to have to be back. The innkeeper's wife is nearly in tears. Another bolshy customer turns up, and is so in her face that the proprietors give up their own room.
Then Mary and Joseph arrive on the donkey. It's pretty much a riot in there at this point. They desperately ask for somewhere, anywhere, please, the baby will be coming any moment now. There isn't even standing room only left. The innkeeper's wife is appalled. She has nothing to offer. She asks if anyone else will give up their room, they all refuse. Falling to her knees, she begs forgiveness that she has nothing better for them, but please, if the stable is any use to them, please use that.
There you go. No cheesy pop music. Story alternative but recognisable. Needs the dialogue, but easier to right than redoing lyrics. And no copyright issues.
