For your enjoyment, here are the lyrics of the pub song from the screenplay which can be found online. I am assuming that this was before Paul Giovanni ended up with the version we see/hear in the movie. I can't find any references to it on the net. Does anyone recognize any of it?

It's all choruses.

CHORUS
A land lord had one daughter
And a nice young girl too she was
Above her garters I dare not go
I being a stranger I fell in danger
For doing so, for doing so.

CHORUS
I sowed some seed, all in some grove
All in some grove, there grows no green
Now for to repeat I could not stir
I being a stranger, I fell in danger
For doing so, for doing so.

CHORUS
When nine long months was gone and past
This pretty girl had a fine son at last
Now she must keep it and call it her own
And reap the seed that I have sown
For doing so, for doing so.
