Searching for an Irish story

Because it is St. Patty's Day, I need a good Irish TG story. Well, there are a few great ones here. But I am looking for one in particular ....

I happened up a story last summer about a company CEO whose software business in Boston was just bought out. His name is Hugh I believe.

He picks up a nice young hitchhiker in Ireland on the way to Dublin. They stop at a B and B. He takes the couch and she gets the bedroom. She is so impressed because of his being a perfect gentleman that she makes love to him. While they make love, she sings a celtic song and they body swap.

Until they can figure out how to undo the magic, the duo go on to Boston where she assumes his role and he, now she, becomes a dutiful "wife."

He, now she, eventually becomes preggers, has a baby, they return to Ireland where she, as he, starts singing the same song. She, he, stops her because he likes being she and a mother.

Okay, I know I found it on another site. I just can't seem to find it.

Any idea what the story is and where I can find it?

Thanks,

AuP
