Just read Velvel Pasternak's "Beyond Hava Nagila". He's got an interesting history about the song "Tsiyon". (It's in the Gourarie book in the smorg section.) According to Pasternak, the original lyrics were "Chasdei Hashem". When some yeshivah bochurim were jailed for firebombing a pornography shop in Jerusalem, protesters sang te song with the lyrics "Tziyon halo sishali lishlom asirayich?" and that version caught on. The rest, as they say, is history..
Amazon has the book here:
