Thank you Malcolm,

That's a very neat and convenient site - I dowloaded both the PDF images and the MIDI files ... so I can both see and hear that neither of these tunes really relates to the one I mentioned (a pity - I was hoping for a 4-century link!).

I must go get a decent ABC app. onto my own computer - I think I've dodged ABC too long - due to an undue degree of "dots" fixation, and it is a very handy, lean, format that can produce very tidy results! (But I don't think I'm going to start playing from it!)

Regards,

Bob
