True words, Joanne - if I attend a new session, I'll either find out beforehand what the style is or have a quiet few minutes absorbing the "culture". I do tend to avoid the very "pure" sessions that take place, such as those where the tune and only the tune - played by everyone in unison - is ever required. I like to play guitar, and I've spent years accompanying musicians of all types, so a mixed bag of music - particularly with some improvisation from the company - is what suits me. If I do find myself at a rather "stricter" tunes session, then I reach for the mandolin... :-)
