I went to a Chanuka potluck dinner party tonight for my minyan. A fun highlight for me was finding out that one minyan member actually knows by heart the words to all six stanzas of Maoz Tzur. I didn't even know there were that many stanzas. Everyone knew the first stanza, some people knew one more stanza and quite a few knew the English version, but then one member kept singing more and more of the song in Hebrew. I know that he attended a Jewish boarding high school (about 30 years ago), so I'm guessing that he learned all the stanzas for his school choir or something like that.
