Brave Sir Robin

Having had this song wandering lazily through my head quite often recently, due to several various things triggering memories of Monty Python and the Holy Grail, I felt like posting the words.

As Sir Robin sets off on his quest for... whatever it was, he is accompanied by a troup of bards, engaged to commit to history the brave deeds of Sir Robin.
Their tales are as follows:

"Bravely bold Sir Robin
Rode forth from Camelot
He was not afraid to die, oh brave Sir Robin
He was not in the least afraid to be killed in nasty ways
Brave, brave, brave, brave Sir Robin
He was not in the least bit scared to be mashed into a pulp
Or to have his eyes gouged out, and his elbow broken
To have his kneecaps split, and his body burned away
And his limbs all hacked and mangled, brav Sir Robin
His head smashed in and his heart cut out and
His liver removed and his bowels unplugged and
His nostrils raped and his bottom burnt off and
His penis-"
Here the minstrels are cut off by an understandably upset Sir Robin with the words (something along the lines of) "Right, right, I think that's enough music for now" . After a while, they continue, quietly at first.
"He is brave Sir Robin, brave Sir Robin who..."
"To fight and..."
Around about here, Robin and his minstrels encounter a three headed... ogre, or something. The three heads disagree with themselves for a while, possibly about how to kill Sir Robin (I haven't seen the movie in a while, I don't quite remember), and as they argue, Robin... retreats. Bravely.
"Brave Sir Robin ran away
Bravely ran away, away
When danger reared its 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"
Again they are interrupted by a disagreeing Sir Robin... and again they continue.
"He is packing it in, and packing it up
And sneaking away and buggering up
And chickening out and pissing off home
Yes bravely he is throwing in the sponge"
And the last verse is interspersed with indignant shouts from 'brave' Sir Robin of "I didn't! I never did! It's all lies!".
