Barbershop singers

Members of the Mon Valley Chordsmen, a barbershop chorus south of Pittsburgh, perform "Swing Low, Sweet Chariot," an historic African-American spiritual. The chorus is shown at Rehoboth Presbyterian Church in Rostraver Township, Pa. Stay with it until the end to catch the "Elvis moment."
