Shouldn't Have Done That

[Verse] Plans made in the nursery Can change the course of history Remember that Mummy's annoyed, says go and play Don't show your face Stay away all day Shouldn't have done that A small boy and his infantry Marching around so naturally Shouldn't have done that Grows up and goes to school Such a nice boy Obeys all the rules Mummy's proud of that Leaves school to follow his ambition Knows what he wants To be a politician Shouldn't have done that!
