Rural Route 4 is the Missouri-based barbershop quartet that won the 1986 SPEBSQSA international competition. They are known for their signature costumes of matching overalls in keeping with the rural theme of their group in venues where formal attire is expected.

Calvin's son, Wes Yoder, later replaced Don as the group's tenor until their formal retirement in 1994.
