I've got a book called "110 Ireland's best Session Tunes" published by Waltons - cost me £7.99. It's got the melody line and guitar chords, and they also do one specifically for Tin whistle (also 110 tunes). You can also get accompanying CDs if you're feeling rich or need to learn by ear. and there are other books (5 more) for other instruments/styles. Tattie B
