Hi Boo, no confusion, I was the one who mentioned it on 9th March.
Because E was the melody note I thought I would try it, and it sounds OK.
Have since looked at other sheets in F and amazing the variation in chords. Although as you just said, and i was told the same, "there are only 3 dim chords".
P.S. I play all chords between the two F's (organ training)
I'll duck now !!!!!
