In response to Greg's comments -

1) The selection for the practice sessions came from tunes that were already being played in the real life sessions that were going on in the area. As Valmai likes to say "Collected from the wild".
2) YES!
3) YES!
4) Well... this is a practice session. Not everyone has the talent for learning by ear. Just get rid of the dots as soon as you can and they carry a government health warning that they are only a guide, not the law.
4) (reprise) See 1) but that repertoire already did include a lot of local material. Much as we'd love you to use the Lewes Favourites book, it would be shame not to track down stuff from your own area (and produce your own book).
5) Lewes Favourites is out of the public eye so that learners don't have to feel that they are playing to an audience. If anyone is drawn in by the music, they aren't turned away but they are warned that it is definitely a practice not a performance.

If Les's session is in the bar he may have to have different rules.
