When Don Knotts came to my college, I was the lucky one chosen to accompany him on his Baseball skit during his show! He was charming, gracious and sweet. He did the following skit, while I played "Take me out to the Ball Game" on the grand piano, offstage. I was in the SHADOWs of backstage. Later people had one of two reactions. Either they wondered why I wasn't on stage to be seen. Or they wondered why I didn't take a bow by the curtain.
I didn't need that kind of attention and was just tickled to do it! What would your reaction been?
