I'm about to transcribe this from a gif sent by John_in_brisbane - but the sum total of the lyrics we have for this are:

The saddest sound I've ever heard
Is the song of the humpback whale
HIs moans and sighs and his eerie cries
Sing a sad familiar tale
For he sighs and blosw as if he knows
His race is nearly run
And that soon with all of his kind he'll fall
Before the whaler's gun.

Anyone have more? Please?
