What's a long lost tv show/movie that you remember by memory but forgot the title?

There's this one musical film I think, I remember my mom said it was Polish because of the names in the credits. I caught the literal last ten seconds of that musical a few years ago. I don't know when exactly, and since it wasn't what I planned on watching I didn't check the title. It looked really old, and the colors were very vibrant, and the costumes were whimsical and to some extent tacky. The credits rolled over a final scene of the characters singing, I think there was a rather tall woman in the middle. The only line from the ending song I remember was "And I just want to exclaim", sung in English, and the rest of the song was probably in English too.

I've always been curious as to what exactly that musical was, and if I can watch the full thing.
