CotD: Extremely similar to a WB cartoon staring Bugs Bunny, “The Cat Concerto” and Tom and Jerry ended up winning the Oscar that year– Bugs would wait another ten for his.
The Cat Concerto (1947) — Tom and Jerry Theatrical Cartoon
Tom is an acknowledged master pianist primed to give his greatest performance of Liszt’s Second Hungarian Rhapsody. As he prepares and finally settles down, ready to play, Jerry is determined to disrupt Tom’s concert. Jerry pulls on the strings inside the piano, slams the shutter on Tom’s hands, and generally runs amok. Tom fights him with the piano without missing a single note.
