AH Clinton, thanks so much for "decoding" that roll! I had it most mysteriously "dawn" on me while I was out for my walk this morning that maybe the letters stood for the RH fingers -- T = thumb etc -- Just got back and here you've confirmed it for me! :>)
Hey, maybe we "connected" through that "psychic void" of music !! ;)
Sounds like you've got quite the flock of Seagulls there! Must be great fun keepin 'em all fed and happy!
