And NOW for the words!! A truly miserable, even slightly spooky, song - enjoy/wallow!
I believe it was one of Burns' last poems, written when he realised that his health was failing, and days might be numbered.
"I had taken," says Burns, "the last farewell of my friends, my chest
was on the road to Greenock, and I had composed the last song I should
ever measure in Caledonia--"

The Gloomy Night Is Gathering Fast

1.
The gloomy night is gath'ring fast,
Loud roars the wild inconstant blast;
Yon murky cloud is filled with rain,
I see it driving o'er the plain;
The hunter now has left the moor,
The scatt'red coveys meet secure;
While here I wander, prest with care,
Along the lonely banks of Ayr.
2.
The Autumn mourns her rip'ning corn
By early Winter's ravage torn;
Across her placid, azure sky,
She sees the scowling tempest fly;
Chill runs my blood to hear it rave:
I think upon the stormy wave,
Where many a danger I must dare,
Far from the bonie banks of Ayr.
3.
'Tis not the surging billows' roar,
'Tis not that fatal, deadly shore;
Tho' death in ev'ry shape appear,
The wretched have no more to fear:
But round my heart the ties are bound,
That heart transpierc'd with many a wound;
These bleed afresh, those ties I tear,
To leave the bonie banks of Ayr.
4.
Farewell, old Coila's hills and dales,
Her healthy moors and winding vales;
The scenes where wretched Fancy roves,
Pursuing past unhappy loves!
Farewell my friends! farewell my foes!
My peace with these, my love with those --
The bursting tears my heart declare,
Farewell, my bonie banks of Ayr.
