The Jewish a capella group Shir Soul performs a medley of Hanukkah music--Dreidel, Mi Yimalel, and Maoz Tzur. This video can also teach about the different lines in music (melody, harmony, bass, and rhythm).
Chabad provides a recording, Hebrew lyrics, translation and transliteration of this traditional Hanukkah song. Maoz Tzur is sung when lighting the menorah.
