AN BUINNEAN BUI (The Yellow Bittern) by The Long Kesh Ramblers

An Buinnean Bui that ne'er broke out
on a drinking-bout Might as well have drunk
For his bones are thrown on the naked stone
Where he lived all alone like the hermit
An Buinnean Bui, I pity your lot
Thou they say that a sot like myself was cursed
I was sober awhile, But I'll drink and be wise
For I fear I might die before my time

And its not for the common bird that I mourn
The blackbird or the crake or the crane
But for the Buinnean Bui who is shy and apart
And to drinks in the mire from the lone bog-drain
If I had known you were nearing your death
While my breath held out I'd have run to you
With a splash from the Lake or a drink from the mire
But I fear I might die before my time
