Guest, PB:
My only ambition's to die in a pub,
Surrounded by women and liquor and grub.
You'll hear all the angels, "Saint Peter," they'll shout,
"Come and open the gates for this drunken old lout!"

First two lines:
Dying in a public house is my one ambition
Feast and drink as I carouse girls I proposition

I think the scansion's right, but I shouldn't end a sentence with a proposition!

Next two lines:
All the angels then will shout; "Open up! St Peter"
There's no reason to keep out this young lotus eater

Again, okay 'old' would scan just as well as 'young'
