The Folksmen
The same trio of actors (Guest, McKean and Shearer) also portray the fictitious American folk music revival band The Folksmen, who first appeared on the November 3, 1984 episode of Saturday Night Live. Some Spinal Tap concert appearances in the 1980s and beyond have even featured Guest, McKean, and Shearer opening for themselves as The Folksmen. The folk trio is also featured prominently in the 2003 Christopher Guest-directed "mockumentary" film A Mighty Wind.
