The Black Watch is a Scottish military regiment founded in the 1700s and legendary for participating in almost every military conflict since. Most recently, its members were serving in Iraq and became the focus of political controversy after the US Army asked the British Army to do things it didn’t necessarily want to do. This critically acclaimed touring production from the National Theater of Scotland, based on interviews with Black Watch members and involving “movement, music, and song,” has both theater people and military people in Seattle buzzing. That confluence doesn’t happen often. (Paramount Theater, 911 Pine St,, 7:30 pm, $55, through May 5)
