The first verse of this song is:

When that she saw her love, happy was she
She knew not what love was nor how to deny
But she made too much freedom of her love's company
Saying "My generous lover, you're welcome to me."

I have the full text of what I first heard from Bert Lloyd and subsequently from Dolores Keane and Frankie Armstrong - their source was almost certainly Bert and he said he had not seen it in print. Does anyone know anything more?

I'm about to go on holiday for a while so may not be able to acknowledge any help immediately.
