This is an optimistic (by Irish standards) love song in the key of A minor. It’s often played fairly up-tempo, in 4/4 time, maybe as a drinking song. Here I’ve slowed it down and set it in 3/4 time. Much more poignant, I feel.
The chorus is:
From Bantry Bay up to Derry Quay
And from Galway to Dublin Town
No maid I’ve seen like the brown colleen
That I met in the County Down
