It's opening night at the Beacon Theater on Broadway in New York City. The house is packed, the warm-up act has just finished, and the featured band is about to go on. Just then, the band leader notices that his newly hired lead singer, a lovely 20-something lass with a sweet but powerful voice, is visibly sweating, shaking, and even sobbing. Her last gig before she joined the band was in a church coffee house in Iowa City, and now here she is about to make her Big Apple debut. With less than a minute to go, and wanting to reassure her, the band leader puts an arm around the young woman and says, "Don't worry, honey. Just be yourself and they'll love you. Remember you have enormous talent. And anyway it's natural to be a little nervous right before a show. We all get that way. In fact, I challenge you to name one person who ever appeared before a crowd without having cold feet."
