Here's something I've asked a few people. I'm thinking of getting a concertina, not (initially at least) to play melodies, but to play chords under my singing; the effect I'm after is something like Johnny Collins's Wind and the Rain or John Kelly's Polly Vaughan.

I'm thinking English concertina (at the moment I sing in whatever key fits my voice best), and I'm wondering about a baritone rather than a treble. Before I lash out a couple of hundred pounds on a Jack, for those who know about these things, does this sound like a good idea?
