that book on session etiquette belongs in the bin. the people Ive seen touting it and 'session etiquette' are the same ones that phoned up a friend of mine and told him not to come again. (my friend was quite hurt by that and almost stopped playing as result.) (and yet hes a fine player, has a huge repertoire, and more experience than any of them, but he didnt fit in to their 'groove')

(the other guy in town runs a session where the only tunes that are played are ones on their list - youre welcome to join in but dont expect to start a tune- this is the same guy that came to my session and played his tunes for over an hour.) as Ive said before etiquette is just common sense - being mindful of others.

Ive played in many sessions, in Canada, US, Scotland and Ireland - and still I consider calling someone up and telling them not to come again worse than any breach of 'so called etiquette'.
