Sean Altman of Rockapella – from the “Where In The World Is Carmen Sandiego?” television show – debuted this comedic band a decade ago and has since performed to sold-out audiences in 25 major U.S. cities. His original songs include the Passover song “They Tried to Kill Us (We Survived, Let’s Eat),” which was featured on NPR’s “Fresh Air” with Terry Gross, and the dysfunctional Bar Mitzvah anthem “Today I Am A Man.” Information is here.
