Can't Stop Singing reports on the contemporary world of old-fashioned barber shop vocalists. Traveling to the Barber Shop Harmony Society's 60th annual international competition, the filmmakers catch quartet crooners in harmony, conduct interviews with the singers, and document the activities of the festival. The video provides a brief history of the quartet phenomenon and investigates the art's current popularity. Quartets, including Fred Revival, Bank Street, Turning Point, the Alexandria Harmonizers, and the Vocal Majority, perform songs.
