Mickey leads an 8-piece orchestra (that's counting the bass played by three birds as one) through the most recognizable parts of the Poet and Peasant Overture. The setting, as the title implies, is a barnyard, and some of the instrumentation reflects that (including various animals used as instruments, like a tuned group of piglets whose tails Mickey pulls).
