You'll get the words on the album Common Ground, where Elvis Costello sings it well.

A few translations: "They sweated their duds till they riz it" - they pawned their clothes till they raised the price of it; "the squeezer" - the gallows; "a sneezer" - a few pinches of snuff; "gob" - mouth; "glims" - candles; "that's all in my eye" - that's all nonsense; "knob" - head (in this case); "jack ketch" - the hangman; "they mind not such trifles a feck" - they don't mind such trifles a bit; "tip us the deck" - get out the cards; "napper" - head; "soon I'll demolish your noddle" - soon I'll demolish your head; "and leave you your claret to drink" - leave you your blood to drink...oh, for goodness sake, this is going on and on. Someone else finish it.
