Thanks Jerryghr,
Went on You Tube and had a look.
What I learned was quite helpful - just need practise now.

My present piece was not by a music publisher but someone helping me out because the dots were out of print.
I've found a lot of classical music just as bad and it gives you a headache when you see it in Musescore.
The price I pay for not playing by ear.
I use a Lenovo 14" convertible for reading music, using Power Music Pro, and it's fine for reading most scores - just the odd piece gives problems.
