Just now I saw a clip on Youtube, I can't believe its available - I thought its protected by copyright. Man, my memories are being refreshed and I love this clip! I was right I knew this piece was used in Tom and Jerry - nobody can forget a great music and a great animated short.
Academy Award winner - Best Animated Short 1946
An interesting note:
Classic Warner Brothers cartoon made in 1946 featuring Bugs Bunny playing the piano.
The plot and execution are very similar to a Tom & Jerry cartoon that was made and released the same year by MGM called The Cat Concerto. Both studios sued each other for plagiarisms, claiming that ideas were stolen from each other.
It's interesting to compare the two.
