Jerry runs into the Metropolitan Opera, trying to evade Tom. The cat disguises himself as a violinist, with a tape recorder (playing the music of “Carmen”) hidden in his fiddle. But Jerry plays it in reverse, and the conductor breaks the offending instrument over Tom’s head. When Tom conducts the orchestra, Jerry sends a score of ants scurrying onto his music sheets, and poor Tom has a hard time differentiating the bugs from the notes.
