During my work on "English International" I spent many hours listening to most of Alf Edwards work.I was lucky enough to have access to most of the early recordings of his playing, which I thought was more representative of his abilities as an English Concertina player.
All the recordings of his playing was to a high professional standard, but his accompaniment for singing was very basic compared with what he was capable of.If you listen to the very high standard achieved by Iris Bishop on her Duet Concertina there is no comparison,but what Alf did (mainly single note at a time) was effective for what was required.
I chose Mitzi (recorded 1951)and Russian Rag as examples of what he could do.These both came from the Stephen Chambers collection.
I strongly recommend that you purchase this three CD collection as examples of styles and music for the English Concertina with recordings back to about 1935.
