Diatonic Liaisons, Alexandra Browne

Alexandra Browne has re-released her Diatonic Liaisons tune book (last in print about 13 years ago). It features tunes by Frédéric Paris, Dave Roberts, Bruno le Tron, Alain Pennec, Alan Lamb, Andy Cutting, Trevor Upham, and Marc Perrone. The tunes are in sheet music (not tab), and in the various keys of various accordions, THUS, it seems like someone with a concertina would be able to make more ready use of this book than I can with my two row G/C boxes.
