It seems that the limited characters that I've seen are mostly singing or performance images but any help on identifying this font would be much appreciated

Thanks

It's just an educated guess, but I suspect that is just clipart, Anthony. The fact that I find the letters on their Pulse Choir web page in an old ClickArt catalog supports this.

Many thanks Mike, do you think that the COHS that appear on the file I uploaded have just been 'cobbled' together? If so I'll stop looking for the complete set.

If I'm right, there may well be a whole clipart alphabet.

I don't know for sure that it's clipart - but it surely is not a font.
