I didn't intend to be cynical, was actually wondering whether going to a session, or some sessions, to practice guitar (or on the same logic any other instrument) might not be a bit anti-social. They might prefer you to wait until you had got yourself sorted out a bit. Like Jon Freeman says.

There is so much free guitar tuition on line nowadays and some of it is very good.

"...the old musicians never seemed to practise or even play, except to contribute to the concert/dance." Not sure what the intended point of this comment is; I'm thinking nobody had got to be a musician without practising at some point.
