My stutter isn't that severe and I have noticed it is almost non existent if I have something memorized and am performing in front of a crowd. They may not even be able to notice I have a stutter, but it is the fear that I will have a really bad one that will completely destroy the energy of the show that makes me want to tell them. That video you shared is inspiring and I will try to get my set video taped and will post it here!
