I play the harmonica as well as the english concertina, and I am in fact a munster champion, but I could never get on with an anglo.
    all three systems have been used successfully for songs and playing Irish music. my C D BOXING CLEVER, features John Kirkpatrick Singing with Anglo, Tim Laycock singing with Duet, myself singin with English and Duet, Harry Scurfield singin with anglo,irish tunes played by myself on English, With Harry Scurfield providing chordal accompaniment on the anglo.
a very interesting player is Keith Kendrick who plays both Anglo and english,but not at the same time.
