Tootler,I agree,the Anglo is versatile,to get all the chords it is better if it is tuned in Equal Temperament.
there is also the concertina compilation Boxing Clever,which features anglo concertina virtuosos Harry Scurfield and John Kirkpatrick,this is available from myself or the Button Box.
.the recording quality[imo]is better than on some of the tracks on anglo international[eg Fred Kilroy]
