Lisa Loeb is Jewish, and (Natalie) performs her song, "Light". Loeb describes the song as "a beautiful song I wrote a few years ago; Sirius XM Radio wanted a Hanukkah channel but didn't have a lot of Hanukkah songs," Loeb told Jewlish. "So they called and said 'hey, would you be interested in writing one?' It was right up my alley because as a Jewish person, and as a person who is interested in religion in general, I think it's so interesting to find the essence of a holiday."
