wanderer's right about Mr Happy's 'Old MacDonald', as I've mentioned before in other threads.

This has reminded me of a parody of 'Ruby, Don't Take You Love To Town' which I wrote a few years ago and can't find a copy of now.
All I can recall is the beginning:

Ruby, Don't Take Your Love To Crewe

You've sanded down your face and stuck your hairpiece on with glue,
Ruby, are you contemplating travelling to Crewe?
And getting pissed on Pernod in the way you always do?
Oh Ruby, don't take your love to Crewe...

I may take that as the starting point and write it again. Often results in a better song, I find.
