On Paul Whiteman—
During the 1930s Whiteman had several radio shows, including Kraft Music Hall and Paul Whiteman's Musical Varieties, which featured the talents of Bing Crosby, Mildred Bailey, Jack Teagarden, Johnny Mercer, Ramona, Durelle Alexander and others.
In the 1940s and 1950s, after he had disbanded his orchestra, Whiteman worked as a music director for the ABC Radio Network. He also hosted Paul Whiteman's TV Teen Club from Philadelphia on ABC-TV from 1949–1954 (with announcer Dick Clark), and continued to appear as guest conductor for many concerts. His manner on stage was disarming; he signed off each program with something casual like, "Well, that just about slaps the cap on the old milk bottle for tonight."
