O'Keefe was born in Hartford, Connecticut. He attended the College of the Sacred Heart in Wimbledon, London before entering the University of Notre Dame in South Bend, Indiana in 1916. At Notre Dame, he was a member of the Glee Club and a Class Poet. He graduated cum laude in 1921.

O'Keefe began as a vaudeville performer in the midwest for several years. In 1925, he went to New York City and became a Broadway performer. By 1937, he wrote a syndicated humor column and filled-in for such radio personalities as Walter Winchell, Edgar Bergen, Don McNeill and Garry Moore. He became the long-time master of ceremonies of the NBC show Double or Nothing and was a regular on that network's Monitor series.

O'Keefe also worked in television, presiding over talk shows and quiz shows for the CBS network. Producers Mark Goodson and Bill Todman hired him for their game show Two for the Money. When the show's usual host Herb Shriner had other commitments during the summer of 1954, O'Keefe took over for three months. He was the host for the first Emmy Awards ceremony, held on January 25, 1949 at the Hollywood Athletic Club. He replaced the original host, Rudy Vallée after he left town at the last minute.

O'Keefe wrote the musical scores of several Hollywood films. He introduced the popular song "The Daring Young Man on the Flying Trapeze" in 1934, and it became permanently associated with him.

O'Keefe became addicted to alcohol, and sought treatment in Cleveland, Ohio during the late 1960s.^[1]

He has a star on the Hollywood Walk of Fame in the category of radio. He died in Torrance, California of congestive heart failure at the age of 82.
