As far as advice on setting up house concerts goes. I find if the host is enthusiastic about who they're bringing in, it helps attendance. If you are hosting, you have to twist arms,let people know they are in for a good time. Fox Valley Folklore Society presented Judy Cook a couple years ago. I handed out flyers at the song circle on a capella night and said if they liked the singing there, they would love to come and hear Judy. It worked out very well. Invite about 1/3 more people than you really want to come (some folks, say they'll come and don't show up, others that you've never met, will come) and you should have a good turnout.
