Of course Constant Lovers is the other book - it should be burnt into my brain!
Frank was also the leader (I think) of The Bampton Barn Dance Band, and yes he played for any or some or most of the Bampton Morris teams over the years when he could or when asked.
A lovely quite man who did so much behind the scenes in both the song and morris world and in my experience never pushed himself forward.
I don't remember any concertina, but certainly he played Melodeon.
