Growing up Mary Poppins was my favorite movie. I used to watch it all the time until my mom took it away when I was 7 because she was annoyed by it. I may be a penguin lover now, but back then it was the whole Mary Poppins character that I liked. Nowadays it remains a favorite and partly because of the fun scene with the animated penguin waiters dancing with Bert. I recently got the new 45th anniversary DVD release version and really enjoyed watching it on DVD for the first time, especially since it is loaded with special features including an audio commentary.
This penguin scene also appears in the Sing-Along Songs: Supercalifragilisticexpialidocous video. The DVD release of this is not all that great, as it is simply the same as the VHS release with no special features.
