Damn, I've been looking for this for years. Heard a guy named Simon Spalding sing it at Mystic ten years + ago.

Some difference: He doesn't sing the line "a-firing the Mauretania". The chorus is just:

She surely was a slaaaaaver...
Ahhhh, to hell with the Mauretania.

And the third line of the second verse was "they worked us like slaves both day and night".

Can't remember, the ending might have been different too.

But I think Simon said he got the song from Mike somebody from New Zealand....

Willie-O
