One of the best postwar Disney shorts in my opinion is All The Cats Join In from the 1946 feature Make Mine Music. It is only four minutes long, but highly enjoyable because of Goodman's energetic music and fantastic animation by Fred Moore, Milt Kahl and others. Each time I watch this short, it puts me in a good mood.
A couple of Moore model sheets with loose, but solid and appealing drawings.
I am not sure who story sketched the film, but these drawings presented terrific inspiration for the animators.
The one thing that doesn't quite work for me are close up scenes, where the characters' black dot eyes look somewhat unsettling.
A design concept for the film's poster.
