Last year, randomly, Mormon senator Orrin Hatch did a great mitzvah for the Jews of America by adding "Eight Days of Hanukkah," which he wrote, to the historical treasury of songs about Hanukkah. Along with Adam Sandler's classic "The Chanukah Song," it brought the total all the way up to two. As the Jews say on Passover about a similarly generous thing that God did awhile back, "It would have been enough for us." Yet now our cup of Manischewitz runneth over, for Yeshiva University's a cappella group, the Maccabeats, have provided Jewry with a third song about Hanukkah. If you are one of the 900,000 people who have already experienced the slickly produced video on YouTube, then you know that it is based off of Taio Cruz's "Dynamite," and you also know a lot more about the story of Hanukkah.
