Hi Ian,
I remember this one from before. You've really polished it one up since I last heard it. It gleams now! As I was listening, the thought popped into my mind that the verses have a Bobby Goldsboro quality to them.
I think what Beagle might have been referring to is a bit of a melodic tussle between the two solo instruments (one MIDI and one RT - at least that's how I heard it). Have you tried the song with only the RT Harmonica?
There are two things that I really really like about this song. One is the form. AABA always feels comfortable to me when I listen to it. Maybe because there's so much Verse-Chorus form around these days that the change is pleasant to my ears. Also these lyrics are a credit to you. They rang with emotional truth. I particularly like the second person narrative perspective that you've used. It's not a point of view but it always works incredibly well when you can pull it off and you've managed to do it

It's big "Loved it" from me!
Noel
