Harold "Scrappy" Lambert (May 12, 1901 – November 30, 1987, in New Brunswick, New Jersey) was an American dance band vocalist who appeared on hundreds of recordings from the 1920s to the 1940s. At Rutgers University he was a cheerleader and played piano for a jazz group, the Rutgers Jazz Bandits. In February 1925, he and fellow student Billy Hillpot formed a musical duo impersonating the Smith Brothers. They were discovered in 1926 by Ben Bernie, who signed them to perform with his orchestra. Lambert and Hillpot appeared on many recordings with the orchestra and remained under Bernie's employ until 1928.
