Good sailors sing songs of lassies and bravery and fortune
How the sea fills their hearts with the courage to do mighty deeds
But I'll sing a song of a lad that I met in Jamaica
Who tested the bravest of brave in all seven seas

Chorus:
(It were)
Happy Jack's undrinkable ale
One mighty sup puts the wind in your sail
It's Happy Jack's undrinkable ale

Our captain once tried a tankard of Jack's mighty potion
He seemed alright, so we all went off to bed
We awoke to the screams of our captain way up in the crow's nest
He tried to fly with the wind, but he ended up dead

Chorus

This ale was as black as a night with no moon in December
As bitter as a man who lost his pizzle in May
As strong as six horses, as evil and wicked as Judas
Of Jack's, the worldliest drinkers most surely say:

Chorus

I sailed with a lad who was tall and as wide as a mountain
One half a pint put this sailor down upon one knee
And we watched as he turned as white as the high cliffs of Dover
And threw up old Jack's as a gift to the mighty blue sea
Chorus

I once tried a thimble of Jack's demonic invention
But for the spinnin' I felt that I was alright
I woke with a chicken, two ducks, a lamb and an oxen
By the looks on their faces I must have had a good night

(Smells like)
Happy Jack's undrinkable ale
One mighty sup puts the wind in your sail
It's Happy Jack's undrinkable ale
Happy Jack's undrinkable ale
One mighty sup puts the wind in your sail
It's Happy Jack's undrinkable ale
