MMario, I've not heard any other words to this tune. Here's my attempt at ABC notation:

X:1
T:The Smuggler
M:4/4
K:G
B,D|E3FEDB,2|A4B3A|G3EE2B,2|D6B,D|E3FEDB,2|A4B3A|G2E2FED2|E6GA|B2B2BAG2|A6Bc|B3EE2B,2|D6B,D|E3FEDB,2|A4B4|G2E2FED2|E6||

And the chords:

My [Em]love he is a [D]smugg[Em]ler, he sails upon the [Bm]sea
And I [Em]wish I were a [D]smugg[Em]ler to sail a[D]long with [Em]he
To [G]sail along with [D]he for the [Em]brandy and the [Bm]wine
And [Em]run the tubs at [D]Slap[Em]ton when the [D]moon do [Em]shine

And thanks to Ian and Malcolm for the correction.
