These are the oldest performing arts groups you'll see – ever. Seriously. The Black Watch was founded in 1667 as part of the Highland Watch. They're still fully operational, but we doubt these guys see much action. They're too busy perfecting their arrangements of classic Scottish tunes. Expect full regalia: sporrans, spats, sashes and broadswords. They'll perform with the Band of the Scots Guards, whose existence dates back to the 1640s.
