People were too busy to take photos! And there wasn't any tune learning as such. A lot of time was spent on using the alternative notes on the outside and inside rows to obtain efficient fingering, using parts of (mostly) pipe tunes to practise.
The real tunes were heard during the informal post dinner sessions. For me, the tune du jour (or du soir) was "The Thomson Boys", composed by Freeland Barbour, and played by Brian.
You should have been there!
