Before I saw this, I gave the Original Polish version a listen, and… unfortunately the Japanese Version won me over. Sorry, @PolandIsAStateOfMind@lemmygrad.ml.
Also sorry for linking Ingen, but he seems to be the only one with English Subtitles for everyone here to understand.
EDIT: Nevermind, the Original Polish Warszawianka’s also just as good (especially the one you suggested, although it’s kinda short). I just at the time didn’t notice the similar melody the JP Warszawianka had.
