About bad nerves and stage fright. Suppose you go out to give your performance and everything goes to hell in a handbasket. The page-turner gets the hiccups, the stage lights go out, you sit down in front of the or-chestra only to discover that your zip is half down, your shoelace is broken, your bow tie is in your other jacket, you brought the wrong score to church, you are suddenly TOTALLY hoarse from allergies. Etc, etc, etc, etc, rinse, repeat.
