 World-famous opera singer Giovanni Jones is trying to rehearse for his upcoming concert. However, Bugs Bunny s singing bothers Giovanni, who s trying to concentrate. But instead of asking Bugs -- who had been minding his own business -- to desist stop until the rehearsal ended, the ill-tempered Giovanni destroys the bunny s instruments as a banjo and harp (and injures Bugs in the process). Bugs eventually has had enough and gets his revenge ... during Giovanni s concert at the Hollywood Bowl. After using a variety of means to soften the opera singer up, Bugs pulls out the coup de gras: dressed as world-renowned conductor Leopold, the bunny makes Giovanni sing an insipid song (basically to make him look foolish) before forcing him to hold a high note, which causes the amphitheater to crumble on top on the singer. But Bugs (who has since ordered earmuffs, rush-delivered thanks to some very express delivery) isn t through yet: "Leopold" --having spotted a huge boulder teetering perilously above where Giovanni is standing -- gets the singer to blare out his high note once more. The boulder tips over and crushes Giovanni. Bugs  banjo solo "Good Evening, Folks" ties up the bunny s satisfying revenge (and the cartoon).
