Tom & Jerry (Chuck Jones era) S01E02 - The Cat Above and the Mouse Below

Tom is a famous singer announced as "Signor Thomasino Catti-Cazzaza Baritone," who will perform at a concert to sing Largo al factotum. Tom arrives in a very long limousine, and emerges, tossing a rose into a frenzied crowd. He walks on stage to applause, which he interrupts with a simple hand gesture, and begins to sing for the audience watching. While all of this is taking place, down below the stage, Jerry is trying to sleep but is awakened by Tom's operatic tones.
