    Her eyes were blue and her hair was brown,
    One night on the grass I got her down
    And I'

The rest of the words were lost to view as he turned a bend in the road.

Btw Father Sidney McEwen was an Irish teno, well that's what I was told in the national school.Having listened to the this clip I tend to agree.
