Well..I did say that I'd probably enjoy that song both ways - but moreso with just the tune on the concertina, which I see as more trad. Let me put it another way, strictly hypothetically, if a pop/rock band was to come to me saying we could do some of those songs of yours in a rock-style, so join us - but you MUST learn to play chords on keyboards, not just your beloved top-line melody, then I would accept that, as the pop/rock style, and start learning more about them. BUT, prefering folk as I do, I keep working at the TUNES. Again, having read all on this thread, it's wrong to say English traditional music is ALL about the tune; but it's not wrong to say it's MOSTLY about the tune.
