I remember somebody singing it on the Hogmanay TV programme. Could well have been John Grieve:

I am sad and weary, very far from cheery,
Sing an eerie, drearie sang that maks yer optics bleary.
Sing a sang of sorrow.
From the Gaelic borrow
The sort of lay that starts today and goes on till tomorrow.

Sing me a Hebridean song, daddy
Sing me a Hebridean song, daddy
One about forty verses long, daddy
Sing me a Hebridean song.

Sing about St Kilda, bonnie wee St Kilda
The only place you'll never find the speculative builder.
Sing to me of Ossian, Ossian was a caution,
He paddled in the ocean while his mother did the washin'.

It was quite a bit longer: I recognise some of the bits from previous responses.
