The Cat Concerto Controversy (Mystery Solved?)

Sorry but this fanciful theory is imcorrect.

The piano playing of Tom the cat was dubbed by Scott Bradley (the Musical Director of MGM's Animation Department) who also made the special arrangement of Liszt's 2nd Hungarian Rhapsody. In some passages, to make it sound extra difficult and impossible for the cat to play while dealing with Jerry, it is arranged for 4 hand piano duet, and this is played by Bradley and John Crown, Head of Piano at University of Southern California in the 1940s and 50s. The score and cue sheets still survive in the MGM archives.
