Thanks, Anglo; I was busy researching/composing my message at the time yours was posted, so I didn't see it till afterwards. And I see Dick mentioned the "EC" but this didn't register as the English concertina, even though that's the type I play. I'd wondered how Tony did such a full yet legato accompaniment: multi-tracking a baritone concertina with portative organ?

Nothing to do with Butterworth, but the tunes do have some similarities.

leeneia, many people may be perfectly happy with tunes of only five notes, but many peopel are perfectly happy with rap, too. When I sing a five-note tune, I get musical claustrophobia. Even an octave seems restrictive. Maybe we just fish in different melodic waters.
