stop me if I've raised this one before but I seem to remember a bluegrass (or pseudo BG) song, hammed up on record by perhaps Spike Jones, or one of his ilk about a shotgun wedding. Went something like:
They're burnin' down the house I was brung up in
They're yellin': "Come on out and meet yer bride"
They're burnin' down the house I was brung up in
But I would be a fool to go outside

There's her pappy by the gate with a loaded .38
And he's shoutin' "Come on out or else I'll shoot"
I don't know if he knows
I've got on his Sunday clothes
If he fires it'll be bye bye to pappy's suit

All I can remember of the rest is:
There's her brother by the door with a loaded .44

Better out than in as my old mother used to say, I'll tiptoe away now and leave this thread to the experts.
