The most popular music show of its time: Your Hit Parade, with musical director Mark Warnow. It ran from 1939 to 1948 on radio, and 1949 to 1955 on television. The sponsor, as you may have guessed, was Lucky Strike. Warnow’s brother was also a musical man: Raymond Scott, whose work appeared in many Warner Brothers cartoons. (He composed “Powerhouse,” the tune you heard any sort of wacky machinery started up. You’d know it if you heard it.) Is musical talent genetically transmitted? The evidence is persuasive.
