Just like many of us, former Facebook exec Randi Zuckerberg participated in a Shabbat dinner this Friday night. Unlike many of us, hers took place in Davos, Switzerland as part of the World Economic Forum attended by global power players. Oh, and while we were trying to get our kids to join in an off-key rendition of “Shalom Aleichem,” Zuckerberg was serenading Israeli President Shimon Peres and Prime Minister Benjamin Netanyahu.

According to Page Six the author, CEO of Zuckerberg Media and sister of Facebook founder Mark Zuckerberg grabbed the mic and performed “Yerushalayim Shel Zahav” in front of the crowded room.

Apparently Zuckerberg has some musical experience, both as a former member of a Harvard University singing group the Harvard Opportunes, and current member of Feedbomb, a band composed of past and present Facebook employees.

Video of the Sabbath concert has not yet been circulated, although we were able to dig up footage of Feedbomb doing a “Call Me Maybe” parody titled “Fund Me Maybe,” which has to be  just as entertaining.
