Brave Sir Robin ran away.
Bravely ran away away.
When danger reared it's ugly head,
He bravely turned his tail and fled.

Yes, brave Sir Robin turned about
And gallantly he chickened out.
Bravely taking to his feet
He beat a very brave retreat
Bravest of the brave, Sir Robin

He is packing it in and packing it up
And sneaking away and buggering off
And chickening out and pissing off home...
