A group of musicians at Indiana University Bloomington turned an ordinary lunch hour into an unforgettable surprise when they staged a flash mob performance right in the middle of their college dining hall.

Andy Morris sat down at the piano and started playing. That was it. Nobody around him knew what was coming. But then a saxophonist stood up from a nearby table. Then another. Then a trumpet player started making his way through the aisles.
A violinist appeared near the center of the hall. Students started looking around, confused at first, then grinning. And just when everyone thought they had seen it all, a man in a full formal suit stood up from his seat and lifted a tuba.
The room lost it. That deep, booming sound filling a college cafeteria is not something you forget.
Students dropped their forks. Phones went up everywhere. People were clapping, cheering, completely caught up in something nobody planned to be a part of that day.
When all the musicians finally gathered around the piano for the big finish, the whole room gave them a standing ovation.
