To continue the verses to Tony's version:

I wish I was a butterfly
I'd 'light on my love's breast
Or if I was a blue cuckoo
I'd sing my love to rest
Or if I was the nightingale
I'd sing till daylight clears
I'd sit and sing for you Molly
For once I loved you dear.

I wish I was in Dublin
All seated on the grass
In my right hand a jug of punch
And on my knee a lass
I'd call for liquor freely
And I'd pay before I go
I'd roll my darling in my arms
Let the wind blow high or low.

I learned this from the singing of Mick Hanley first, then heard it by Triona Ni Dhomhnaill. I think the versions are very similar, if not the same. Margaret
