I know that when I went and saw Wicked, I wanted to applaud for Shoshana entering because it's the first time we see our heroine! And I knew Shoshana was going to be great, so why not show her right away that you love her? I don't mind it so mcuh...I just don't like it to last a long time; show your appreciation and then let them carry on.
I know that if I was a performer and I walked out on stage and the audience applauded my presence, it would be a very positive experience. Of course, you have to learn where positive reinforcement like that transforms into egotism in the actor and know where to draw that line. For instance, Carol Shelley walked out on stage and I could tell she was expecting the applause, so I didn't give it to her. And neither did anyone else. And I'm glad I didn't because she was pretty awful, overall.
I applauded George Hearn--'cuz, I mean, come on, it's George Hearn--but not many other people did, I think because not many people knew his significance.
In short, I like entrance applause.
whatever and ever amen - ben folds five
