Tote your cool kid and her friends to Williamsburg for an hour-long concert where the group can jam to live music. The band will sing “Happy Birthday” onstage, and the birthday rock star gets a signed copy of the show's set list. Past themes have included “The Music of New Orleans” and “Outlaw Country,” with Johnny Cash and Willie Nelson covers. Three packages cover admission and cupcakes, and two include Blue Ribbon French bread, pizza and juice. Ages 1-10.
