Dave, Dominic also wrote a parody: One part I remeber is:

How many of your best friends are Jews,
In an English Country Garden,
If jackboots were marching which would you choose,
In an English Country Garden,
Israel or Palastine,
Jesus Christ or Einstein,
Which one, what one, slowly take your time
And maybe we will go to tea, benath the gallows tree,
In an English Country Garden.
