Possibly a more inclusive approach folkwaller's club night organizers could take, if they wished, might be to show those whose setup is annoying or open to disaster that there are more audience-friendly ways to do it. Heck, even run a workshop on it including practice runs with a timer. The club workshop's organizers can decide their acceptable time limit; I suggest more than 2 seconds to set up lyrics is too long unless you are pro enough to completely hide it in your introductory story/joke (not a joke about slow setup please). The problem can be solved with sticky tape and pre-set height for one's music stand. But obviously not everyone thinks ahead that way, else there's be no thread here!
