If you take the riffraff from the pub and inject them into the library, you're going to have a bad time. According to Kevin Creehan, his grandson, Irish fiddler Junior Creehan was always amazed that Irish Traditional music became a thing for pubs. To him, it had started out as thoughtful people gathered around in their kitchens playing music together. I can attest that a trad session can be a contemplative and even a bit trance-like.
