who started singing take me out to the ballgame
Seventh-inning stretch There is no certain date when the tradition began, but the practice gained exceptional notoriety from broadcaster Harry Caray. Caray would sing the song to himself in the broadcast booth during the stretch while a play-by-play announcer for the Chicago White Sox. After hearing him sing one day, White Sox owner Bill Veeck Jr., the famed baseball promoter, had Caray's microphone turned on so that the ballpark could hear him sing. When Caray moved into the Chicago Cubs broadcast booth, he continued the practice, sparking what has become a Cubs tradition by regularly leading the crowd in singing the song in every seventh-inning stretch. Since his death, the Cubs have invited various celebrities to lead the crowd during the stretch, including James Belushi, John Cusack, Mike Ditka, Michael J. Fox, Bill Murray, Dan Patrick, Ozzy Osbourne, Eddie Vedder, Mr. T and Billy Corgan.
