Well, I have found the tunes by searching the internet. Several of them have diferent renditions, close to the same, but somewhat diferent.
How do I know the tunes are "Traditional"? That is a good question. I really don't know how to answer that. If the tune says jig, reel or slip jig, it at least gives you a clue. Some of them like "Da New Rigged Ship" are well know traditional tunes. in the ABC files, the source is usually left out, with a couple of exceptions. These exceptions are usually "I learned that at such and such session", or "Learned at a session, from the fiddlers fake book.
Anything that says it is from something like "The FIddlers Fake Book" I am throwing out. That still leaves me with about 80 tunes.
When I get these organized, any one want a copy? I could post the ABC's.
