Alan et al,
There's a first stanza that Gerry Hallom left off of his setting of the poem, that I've added back when I sing it:

There were ten of us there on the moonlit quay,
And one on the for'wd hatch.
No straighter mate to his mates than he
Ever said, "Old Len's a match!
'Twill be long, old man, e're our glasses clink,
'Twill be long e're we grasp your hand,"
So we dragged him ashore for a final drink
And the whole wide world looked grand...

This was from "The Complete Poetical Works of Henry Lawson", Angus and Roberts Publishing.

Hallom also omitted the last stanza. I have two of his LPs on Fellside Records; they're great collections of both traditional Aussie songs and his settings/recitations of some of the poems by Lawson, Patterson, Thatcher and others. Rumor has it he did a third album, but it never made it to our part of the US.
