The Crew-Cuts were a Canadian vocal quartet that reached prominence in the 1950s, consisting of members Rudi Maugeri, John Perkins, Ray Perkins, and Pat Barrett. Known for their smooth vocal harmonies, they specialized in a style of popular music often referred to as "doo-wop". The Crew-Cuts are most celebrated for their hit cover versions of original R&B songs, with their most notable single being "Sh-Boom", which topped the Billboard chart in 1954. Their interpretations of African American music played a significant role in bringing such music into the mainstream.
