I think the problem is that Mr Snail believes that the Lewes Arms is typical of the folk club, session and singaround scene in the UK at the moment. My own experience (and I haven't been to the Lewes Arms, but will believe those who praise it) is that it certainly isn't typical. Believe me, I have experienced some toe-curlingly awful times that have led me to the conclusions set out above.
There was a time when I would make a point of finding out what clubs or sessions were on in any place I was visiting and going to see them. These days I don't bother; the enthusiasm has been beaten out of me by too many stultifying evenings of care-in-the-community ineptitude.
