Here's a jig in G. I learned it from Martin Hayes' album Under the Moon. It also goes by "Cooley's Jig," "Bohola," and "Joe Cooley's Delight" and is often played in D instead of G. (Just move the whole thing over a string.)
It's been a while since I learned a tune from Martin Hayes. His playing is so unique you can recognize it immediately. Also, it's hard to shake his influence once I've learned a tune from him. Sometimes if I learn a tune from his playing and then I hear someone else play it, I won't even recognize it as the same tune, even if every note is the same. He plays with a distinct lilt and pace that is his own.
