MacCormack began his radio career in South Bend, Indiana, and in 1930 had his first large-market job with
WIL in St. Louis, Missouri. In 1933, he moved to
WBBM in Chicago, Illinois, where he was "an actor, announcer and producer." He was also the announcer for
Easy Aces,
Hymns of All Churches,
Myrt and Marge,
The Story of Joan and Kermit,
The Wayne King Show,
Woman in White,
Bouquet for You, ''Caroline's Golden Store
, The Curley Bradley Show
and Dot and Will
. Beginning November 9, 1936, MacCormack (poetry reader) and Jack Fulton (tenor) starred on Poetic Melodies''. The program was carried on
CBS. On
WCFL in Chicago, he was host of
A Great Day for Music, and for many years he was the overnight broadcaster on two of Chicago's well-known clear-channel radio stations, first on WBBM and then on
WGN, and thus was heard by listeners hundreds of miles from Chicago. In contrast to the primary sports-and-talk formats of WBBM and WGN, MacCormack read romantic and sentimental poetry and played
classical,
big band and
Broadway music. One poem, "Why Do I Love You?" became his signature, the first line of which he would typically use to begin his program: :
I love you not only for who you are, but for what I am when I am with you. The program was syndicated in addition to its broadcasts on WGN. Columnist Larry Wolters added, "People come from Madison, LaCrosse, Dubuque, Milwaukee, Chicago, and other places to watch Franklyn read his poetry, hear popular and familiar music, to hear him philosophize, and give out information on a variety of subjects." ==Books and recordings==
