I ran a folk club in Northern Ireland which was particularly well endowed with regular floor singers. Some guests made it their business to listen to the regulars, some didn't. My conclusion was that it was good politics for guests to listen. An obvious willingness to be part of the club was appreciated by the audience and usually gave the guest a flying start.

I do, however, understand Harvey's point that after a long journey some peace and quiet to get yourself together is necessary.
