John (I nearly called you Ted), I mentioned your good name just after saying a chorus/harmony? in a folk club can sound great (whatever it is), in my opinion, as you suggested I'm a tad anti-harmony - "You seem to be worryingly entrenched in your anti-harmony views"; Now, I did admit way back that I know little of harmonies and chords (I could recognise some if I could see a guitarist's or pianist's left hand) but (minus a degree in mathematics) I have tried, Marje, and shall do so once more...there's you a soprano, Ted the tenor, and George the baritone singing from the same hymn sheet...and you're looking at the SAME! top-line melody (in A! given key) and listening to the same organ as you do so - you are NOT, thus, singing in different keys/you are singing the same top-line with naturally different (sop., tenor, baritone) God-given voices, yes?
