The document describes an amusing incident that occurred during the Chicago Symphony Orchestra's Centennial celebration concert. As a gift, donors who attended a pre-concert dinner were each given a desk clock, but some of the clocks had their alarms accidentally left on and set to different times. During the concert performance, as the clock alarms started going off randomly due to reaching their set times, the beeping disrupted and confused the audience. It was eventually realized that the source of the mysterious beeping sounds was the alarm clocks that had been distributed earlier.
