Hi Joe, Yes I did check the Digital Tradition Database and unfortunately, none of those are the correct lyrics. Here is part of what I do know...

Farewell to your drinks and ____? Farewell to your diry lying Farewell to your _____ and gangplanks And to hell with your overtime The good ship Ragamuffin is lying on the quay

*cant make out the next few lines at all To the shores of Botany Bay

It goes on from there but the accent is so thick that I can't even guess at most of the words. Thanks for your help.
