Anyone who fondly remembers Harry Caray should click on the site below and check out some of the sound clips. It sure brings back some good memories for me.
Best of all is the "collection of play-by-play clips," which includes Harry's home run calls from two games I was lucky enough to be at: The June 23, 1984 "Sandberg game" (the highlight here is Sandberg's second game-tying homer off Bruce Sutter in as many at-bats, and you can hear Lou Boudreau in the background with Harry); and a 1989 game-winning homer by Mark Grace.
Also in the "collection of play-by-plays" is Harry's call in the late 1984 game in which a Pete Rose grounder up the middle that looked like a sure hit was deflected by Lee Smith to shortstop Dave Owen, setting up an improbable game-ending double play.
I hope the link works:
