This thread seems to confirm the link between Ballyshannon Lane and Dromsnot mentioned above (including Brians wonderful lyrics).

There is also a suggestion that there is a set of lyrics to Ballyshannon Lane itself, but these ar enot provided. I don't know how far this goes in answerign Joe's original query, but the tune of Ballyshannon Lane is bound to be available somewhere on the web. I'll be back if I find it.
