It's the "noodlers" that drive me nutzoid. I sing in a normally loud environment (Jeri knows what I mean! -- oh yeah, and WHO I mean.) I've semi solved the problem by knowing what note I start an a capella piece on and have my husband (sitting next to me at the table) give me the note on the concertina. Once I start, the people who noodle constantly between songs *usually* stop playing. It helps that my husband is session boss. Sometimes it's so loud, though, that I can't hear the note even though I'm right next to him.
