During WWI, he served as director USA Ambulance Service Jazz Band. After leaving the service Hamp became a successful vaudeville performer and pioneer radio artist. By 1931 Hamp was credited as the most highly paid individual artist in radio and newspapers named him one of the most popular and entertaining singers ever to perform before a microphone. In 1936-37, Hamp starred on a transcribed syndicated radio show called "Rhapsody In Rhythm" backed by a great jazz group called The Rhythm Rascals. Selections on this CD are from that show and consist mainly of hit songs from the late 1920's through 1930's. Those not familiar with Hamp are in for a very pleasant surprise and will be quickly won over by his bubbling personality and sparkling style.
