I was curious, and I've found a version of Streets of Derry here:

Does it look like the version that's wanted?

It may be a beautiful tune, but I don't want to work on chords for it, because it moves stepwise so much. It will take more time to work it out than I can afford.

But perhaps finding the sticks and dots will help someone else.
