Here's what I hear:
Our main sail hath shot 'cross the punch(???) or-ange sky
Waves we pass slow, but 40 meters high
Oh the methane blows beneath the bow a 100 fathoms down
As we sail Kraken Mare down home for Vonnegut(???) town
Hey o hey hear the tug of Titan's tide,
Hey o hey smell the whiff of cyanide,
Hey o hey hear the splash of oily foam,
The ghost of hot(???) Saturn says: "You're far from home"
The shores of mighty high(???)land feed the sea with storming(???) stream(s)
A witches' brew of chemistry, it's a madman's fever dream,
And somewhere down beneath the waves in hydrocarbon hell,
God knows what ghost lurks there, maybe Titan krakens dwell
Hey o hey hear the tug of Titan's tide,
Hey o hey smell the whiff of cyanide,
Hey o hey hear the splash of oily foam,
The ghost of hot(???) Saturn says: "You'll never make it home"
The ethane sleet has slammed us up 'gainst a tarry shore
Ice rock ripped through the hull and left a jagged hole
Abandon ship! Now man the boats! Tiz' a chilly place to die!
Flap the long boat wings boys! Haul on those oars and fly!
Hey o hey hear the tug of Titan's tide,
Hey o hey smell the whiff of cyanide,
Hey o hey hear the splash of oily foam,
The ghost of hot(???) Saturn says: "Now here's your(???) only home"
There's definitely a syllable between "of" and "Saturn", and it sounds like "hot", but that doesn't really make sense.
In the last line I hear "only home" rather than "long way" as kamaz transcribed it, but "your" doesn't sound very clear to me, and may be something else (though it fits the context).
