No - unless the events are far enough apart to provide for plenty of time to set-up and tear-down.  On a regular basis we provide music for events during the day (such as cheerleading competitions, dance programs, athletic events) that have a firm, stated ending time.  We will schedule an evening event on the same day, as long as we know for sure that we have plenty of time between both events.  We will inform you of this prior to booking EITHER event and allow you the right of first refusal (unless the event during the day was already scheduled).
