Hart continued to announce with Glenn on a regular basis in
South Jersey, and kept several side jobs as well, including teaching high school history classes in
Medford and
Audubon. When
Philadelphia was granted an NHL expansion team in 1966, Hart submitted his tapes to the team, which would be called the
Flyers. Since the Flyers could not afford one of the more experienced Canadian announcers, Hart got the job. Although he only expected to be on the staff for a few years until the Flyers could afford a better broadcaster, Hart stayed on as the voice of the Philadelphia Flyers for 29 years, from the team's inception until the end of the
1994–95 season. Hart's colleagues as a Flyers announcer included
Stu Nahan and
Don Earle. Known for his rapid fire delivery, Hart's style was heavily influenced by famous ice hockey broadcaster
Foster Hewitt. His signature goal call was:
Tasty Baking Company was (and still is as of 2024) a Philadelphia Flyers sponsor and awards a case of their desserts whenever a Flyers' player scores. The cases are usually given to charity in the player's name. In the early 1980s, he was also one of the voices of the
NHL on USA. His signature phrase, which he used at the end of games, was "Good night and good hockey!" Hart succeeded Hall of Famer Roy Shudt as the announcer at Brandywine Raceway in
Wilmington, Delaware, in 1984. He called the horse races there until the track closed in 1989. Hart and ice hockey historian Bruce C. Cooper co-authored
The Hockey Trivia Book published by Leisure Press in 1984, and his autobiography entitled
SCORE! (co-authored with Buzz Ringe) was published by Bonus Books in 1990. A feature-length documentary film about Hart's life entitled
"All Hart" is in production by Green Creek Films. Hart did the play-by-play for the
1973 Final of the
North American Soccer League (NASL) between the
Philadelphia Atoms and
Dallas Tornado.
