December's Mighty Musical Monday falls on Monday, December 7, 2026, at noon at the Tennessee Theatre, 604 South Gay Street, Knoxville, TN 37902. Free to everyone. The theatre's house organist plays the historic Mighty Wurlitzer alongside rotating local guest artists, inside one of the most beautiful rooms in East Tennessee. Coca-Cola Consolidated is sponsoring complimentary popcorn and refreshments at every 2026 performance. No tickets and no assigned seats, which makes it a forgiving first concert for small children. Little History Lessons runs the same morning at 10:30 at the East Tennessee History Center, directly across Gay Street, so the two stack into one downtown trip.
