What is the sound of an audience eating out of the palm of a performer s hand? Utter silence and that s what you hear while John Denver is singing or speaking during this two hour-plus concert. It s not just that John s performances (part acoustic, part with a string quartet), drawn from his vast repertoire, are flawless; it s also that his manner with the audience is so humble, so engaging, that he immediately creates a hushed intimacy with the crowd, and never more so than when he tells the story of how it was almost he and not Christa McAuliffe who was chosen to be the civilian aboard the ill-fated Challenger mission.
