I'm looking for a good Scottish/Burns songbook. I play a Hayden duet, and lack musical training, but I can read music well enough. I'm hoping that I can easily create duet arrangements from notation with melody and (piano) accompaniment. I need to be able to buy online and, of course, the more tunes per pound, the better. If anyone can offer good advice on converting a piano accompaniment to concertina, that too would be appreciated.
