Can you help me with translation of this song It started with the hay loft a creakin'

Well it just started in the hay (loft)

With his long johns on pop went a creepin'

Out to the barn up to the hay

Young lovers and they are not sleeping

Young lovers in the hay (loft)

With his gun turned on pop went a creepin'

Out to the barn up to the hay (loft)
