NBC's

CBS's
The Doris Day Show, and co-starred with
Larry Storch in a short-lived TV sitcom,
The Queen and I. He often appeared on talk shows and in TV commercials, doing his "Mrs. Murgatroyd" drag routine. Wearing a hat and a shawl (but still sporting his mustache), De Wolfe (as old maid Phoebe Murgatroyd) would claim to be an expert on romance and answered questions from the lovelorn. Generations of TV viewers know Billy De Wolfe only by his voice, such as the voice of the finicky but inept magician Professor Hinkle in the animated 1969
Christmas special Frosty the Snowman. That supporting character speaks with De Wolfe's precise but exaggerated diction: "Mess-y, mess-y, mess-y! Sill-y, sill-y, sill-y! Bus-y, bus-y, bus-y!" In 1967–68 (one season, 26 episodes), he co-starred with Joby Baker and Ronnie Schell in the TV sitcom
Good Morning World as Roland Hutton, the fussy manager at a radio station where David Lewis and Larry Clarke (Baker and Schell) are co-hosts. In 1972, De Wolfe was scheduled to return to Broadway in the role of Madame Lucy in the musical revival of
Irene starring
Debbie Reynolds,
Monte Markham,
Ruth Warrick, and
Patsy Kelly. During the early stages of rehearsals, however, DeWolfe learned that he was ill with cancer and was replaced by
George S. Irving. Nevertheless, later that same year, De Wolfe recorded a vocal track for songs presented on the album
Free to Be… You and Me, which was part of a children's entertainment project developed by actress and author
Marlo Thomas. A related animated special was subsequently produced for television and aired on
ABC on March 11, 1974, just six days after De Wolfe's death. ==Personal life and death==
