Beginning in 1956, the overnight hours were the domain of Holmes "Daddy-O" Daylie (1920–2003), who brought his sense of humor, way with words and musical knowledge to WMAQ as he played cool jazz until dawn. "Daddy-O" was the first African-American hosting a regularly scheduled radio show on a Chicago network owned and operated station. It was WMAQ's Dave Garroway who discovered Daddy-O tending bar in 1947 and suggested he train for work in radio. By 1948, Daddy-O was on the air on Chicago's WAIT. When Garroway discovered Daylie, he was the host of the "1160 Club" overnight on WMAQ, also playing jazz.
