Thanks, Sorcha and Joe!

Here is singable English version (the same one that is in "Rise Up Singing" and "Singing The Living Tradition" [UU Hymnal]).  (I'm out of town without my books, and wanted the lyrics for tomorrow night.)

                                                         Rock of Ages (Maoz Tzur)

                                                         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 wanderers,
                                                         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.

*Some versions use "Thou," "Thine," etc., in lieu of "you," "your," etc.

 

                                                         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
                                                     

BTW, if the song has been translated into Ladino, I'm sure the Sephardic residents at the retirement home where I'm singing tomorrow evening would love to hear that, too!
