Thanks, jazzgirl. Blindingly obvious ... as I thought it would be! (Mind you, it would have helped if I'd spelt Smetana correctly (I am a musician!!) Will always remember you were the first to give me help when I joined the forum.
Well, well ...! Suppose your name suggests what line of music you're in. I've been an organist, leader of church choirs, worship groups etc for (dare I say it?) just coming up to 50 years. Semi-retired now .... well, sort of!
