Passover, or Pesach, is April 12 through the 20th this year. The Jewish a cappella group Six13 (previously at Neatorama) has released their annual Passover pop parody song, and this one is set to the tune of "Apt." by Rosé and Bruno Mars. They call it "PSVR." This video tells of the exodus from Egypt that was the origin of Passover and describes the seder meal, and actually makes a lot more sense than the Rosé song (which has a sort of an explanation in the first comment here). At any rate, this song fits nicely with Six13's extensive collection of pop songs converted to Jewish holiday anthems.
