Early life and career
Drees was born on February 8, 1917 in Chicago. He attended Austin High School and the University of Iowa, where he was an all-Big Ten center on the Iowa Hawkeyes men's basketball team. After graduating, he went to work for WJJD in Chicago as a secondary baseball play-by-play announcer to John Harrington. His first day on the air was May 23, 1938. In additional to baseball, Drees also called National Football League games and horse races from Sportsman's Park for WJJD and sister station WIND. Although he had never seen a horse race prior to calling one, Drees became "the most accurate and respected horse race announcer in the country" according to Jack Brickhouse.
 Los Angeles
After the war, Drees returned to WJJD and WIND, but the stations had dropped their sports coverage. He later moved to Los Angeles, where he called horse races and served as Public Relations director for the Los Angeles Dons of the All-America Football Conference. After the league folded in 1949, he returned to Chicago, where he called horse races and college football.
Drees first television role was co-hosting Pabst Blue Ribbon Bouts with Russ Hodges. His television broadcast of the 1963 Sonny Liston-Floyd Patterson world heavyweight championship fight drew the largest audience in history up to that point. In 1954 he was hired by ABC to announce college football games with Tom Harmon. In 1960 he was hired by CBS to call St. Louis Cardinals football games. In 1967 he called Super Bowl I for the CBS Radio Network. In additional to NFL games, Drees also called college football, golf, and horse races for CBS.
During the 1960s, Drees broadcast the Illinois state high school basketball tournaments on WGN-TV. He also hosted a program on WGN-TV called "Sports Unlimited". He was the play-by-play voice for Chicago White Sox telecasts on WFLD from 1968 through 1972. His broadcast partners were Dave Martin (1968), Mel Parnell (1969), Billy Pierce (1970) and Bud Kelly (1971–1972).
 Later career and retirement
In 1974 Drees and James C. Mullen published a book entitled Where Is He Now? Sports Heroes of Yesterday - Revisited. From 1977 to 1985 he worked for WKRG-TV in Mobile, Alabama. In 1986 he retired to Dallas.
