Maoz Tzur is a song sung traditionally at Chanukah. It is basically "Rock of Ages" with slightly different lyrics and a different tune. My family sings this together every year after we light the candles on the menorah. I did a version of this a few years back that is still popular online, but I wanted to do it again.

Lyrics:
Maoz tzur y'shuati
L'cha na-eh l'shabey-ach
Tikon beyt t'filati
V'sham toda n'za-bey-ach
L'eyt tachin mat-bey-ach
mi-tzar ha-m'na-bey-ach
Az egmor, b'shir mizmor
Chanukat ha-miz-bey-ach
Az egmor, b'shir mizmor
Chanukat ha-miz-bey-ach.

Rock of ages, let our song
Praise your saving power
You amid the raging foes
Were our sheltering tower




Furious they assailed us
But your arm availed us
And your word broke their sword
When our own strength failed us
And your word broke their sword
When our own strength failed us

Children of the Martyr-race,
Whether free or fettered,
Wake the echoes of the songs
Where you may be scattered.
Yours the message cheering
That the time is nearing
Which will see all men free,
Tyrants disappearing;
Which will see all men free,
Tyrants disappearing. (less info)
