Seen the piccies - thanks Vince - yep, I believe that thar Dan's the man!
I can't be certain as I couldn't get in anywhere near, but I reckon so. Our Anne (being very tiny) squeezed through for a close look, but I can't ask her to view the pix as she left for Croatia yesterday!
I did see him stop and seemingly make notes, fill in staves etc - does that help narrow it down?
Anne came back with 'Jings! Wit duz HE need tae write doon?!!'

Hey Kitty, how you doing?
Sorry we never ran into you at Siddy, but I'll see you at Herga on Nov 14th if not before!

Cheers! - HFA
