Ha, got myself a quick break at a coffee shop   - thinks - I may stay for lunch!   Cool ( Bill lets the lads just get on with the work!)

@Gordon Shumway - my apologies Andrew - it's not an actual plug-in - it's an online conversion program - you'll find it here - https://musescore.com/import - just point it at your local pdf file, it will get uploaded, and when converted a "download" button/link appears so you can retrieve what is now a .mscz file.   The converter will have a "pretty good shot at it" especially if it is a nicely formatted (machine generated) score.   It's not always 100% perfect, but most times I have used it, the discrepancies are relatively minor and can be quickly edited manually (well, if I really really wanted to).  Certainly saves having to enter the entire score manually (in which time I probably could have just worked it through a good number of times from sheet)
