1x127 - Tom and Jerry

Jerry runs into the Metropolitan Opera, trying to evade Tom. The cat disguises himself as a violinist, with a tape recorder 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.
