Barry, I'm sure the situation at Mystic will be the same - and from what you've described, the shanty session that you attended is EXACTLY what we are talking about.

The individuals who had the books may not have "soared" and raised the rafters as others did, but from your description they were not made to feel like they were doing anything wrong by using a book - and they probably had a wonderful time. Perhaps next time they will follow the lead and not need a book. Perhaps they will. The main thing I get from your description is that they were given a chance to be comfortable and participate.   I think that is all anyone has said on this thread.

Venues shouldn't "frown" when they see a book, nor should they encourage people to use them. Learn by example and have patience and understanding to help others along.

"Book sings" are not your cup of tea, but they have their place.
