Some years ago our folk group was invited to sing local folk songs at a community street fair. Shortly after our set there was an announcement on the PA. "The children's Community Dance Group are going to perform in a few minutes time near the information tent. They have put in a lot of rehearsals for this so please come and watch them." A couple of us strolled down to the information tent where the kids were ready to go, but no-one else appeared. After five more minutes there was another announcement. "Look, some of the folk people have turned up to watch the kids dance, so why can't some of you normal people come along too."
