I saw this when on The Wonderful World of Disney as a kid, so I didn't recall much of it. As I watched it recently, I sat there thinking, "This is the weirdest thing I've seen".

The 'traveling' scenes look like something caused by an LSD overdose. The animated characters are mostly oddly colored/voiced versions of Jungle Book and Robin Hood characters. Some not-so-Disney things I noticed: kids being threatened at knife point and prostitutes(during the Portobello Road song).

It was very entertaining, though the musical numbers were long and I can see little kids getting bored with them. Also, the subject manner was a bit dark, seeing as it was set during WW2.
