I go through most weeks with a different obsession, and the past month or so I'm on a real Disney kick. But I tried to find this on YouTube, and when I did, I wanted to post it! It's 1946's "All the Cats Join In", and it's one of my favorite 'one-shot' Disney short subjects.
I love all the Freddie Moore characters (I'm sure he animated on this.. or did he just design the characters? I'm not sure), and check out the dancing scenes at the malt shop... Such smooth and fun animation!
