Cara Dillon's version uses two verses added by Maurice Leyden (he says as much in the notes to his CD The Tern and the Swallow). I love Maurice's singing, but as a writer he's not a patch on Nailly himself. There are also a couple of slips in the transcription above - the Blackwater is the name of a river, for instance.

The original lyrics are as follows.

THE TERN AND THE SWALLOW (Nailly Coney)

When the cuckoo is calling o'er woodland and valley
And the tern and the swallow flies over our bay
Then it’s longing I’ll be for the land of my fathers
Where Bann and Blackwater sweep down to Lough Neagh

A home I have made in this land of the stranger
'Tis many's the long year since I left Derry Quay
Still I dream of the bloom in the glens of old Ireland
Where Bann and Blackwater sweep down to Lough Neagh

'Tis grand is the Rio and fair the Ohio
And wide the Missouri of mention I make.
Still an urge makes me follow the tern and the swallow
Where Bann and Blackwater sweep down to Lough Neagh

It’s soon I must start and this is my last journey
For my eyes they grow dim and my hair sparse and grey
And soon I must follow the tern and the swallow
Where Bann and Blackwater sweep down to Lough Neagh

So adieu to the Rio, goodbye the Ohio,
And farewell Missouri so far, far away.
All I ask is a cairn in the land of my fathers
Where Bann and Blackwater sweep down to Lough Neagh
