The Street Corner Singers are a notable example of Doo-Wop, an urban form of music that flourished in the mid-20th century. Known for their tight harmonies and rhythmic a cappella style, they helped to popularize the genre during its peak. Band members such as lead tenor John "Johnny" Smith and baritone Earl "Chubby" Johnson are recognized for their distinctive vocal contributions. Their most influential work includes the hit "Under the Street Lamp," which has been covered by numerous artists and remains a staple in the Doo-Wop genre.
