The first English folksong LPs I heard were Lloyd & MacColl's sea song albums acc. by Edwards.

I'd never heard the concertina before except in the usual movie snippets (and I can't even identify those except, of course, in Moby Dick).

Maybe because it was in the distant past, before the revival had evolved more elaborate (but not always superior) accompaniments, but I found nothing "thin" or disappointing about Edwards's work. Quite the contrary. It backed up the singing with what seemed to me to be the perfect combination of drama, sensitivity, and self-effacing simplicity. That's what gave it its "folk" quality: it didn't seem showy or sophisticated. Edwards supported the singing rather than share the spotlight with it.

Edwards's playing may seem ho-hum to listeners who came to the music after first hearing the more elaborate (and often more rhythmic) arrangements of say, the Dubliners or the Ian Campbell Folk Group, but his chosen style of expression was rather different.
