Buffy Sing-a-Long The Music Box Theatre was transformed into Sunnydale circa 2001 when “The Buffy Extravaganza,” an audience-participation musical tour, came through town. The Box showed the musical episode “Once More with Feeling,” in which Buffy and her cast of supporting characters are forced by demons to sing and dance. The audience was only happy to help out, waving their geek flags high with finger puppets and vampire teeth.
