Unfortunately, those mentioned are for the anglo, and you have an English. I've forgotten whether there's a video companion to Pauline's tutor, but if not, there should be.
I would recommend the "Concertina Workshop" Tutor By Alistair Anderson, for learning to play English Concertina. It was the best book I found when I was first learning to play. It is available from the Button Box. It is a good straight forward tutor with good info and good tunes, and info about chords. Alistair Anderson is a great player of the English. --Try it, you'll like it--PS-when this tutor first came out it had a companion LP,but I don't think it is still available nor been put out on cassestte or CD?---Steven
