Grand Uproar is a 1933 Terrytoons cartoon.
It's a big night in Animal-Land: the opening performance of Der Meistersinger at the Opera House! All the animals dress in their finest for the big night- even the doggies wear top hats! The opera hall goes crazy as the orchestra rises from the pit and keeps on going out the roof and then back down. As the show goes on, more wild events follow. A gang of street mutts sneak in with cartons of rotten tomatoes! The opera commences, and the mutts plaster the villain with tomato paste!
