Depends on what you mean by "exciting".
In 1987 at the Budweiser stadium in St. Louis, the Scouts were on the field when a massive rainstorm hit. They played through their show brilliantly despite the sudden downpour. But when they started play "Stars and Stripes", LIGHTENING STRUCK INSIDE THE STADIUM. It created and effect as though the revolutionary war was on all over again, and it had the audience on its feet. It was like the fireworks from God was suddenly accompanying the show!
