Maybe you never heard him in his prime. No doubt he stayed on the job way too long, but when Harry and Jimmy did the Sox games, nobody was ever better than those two. And when Harry joined the Sox, he had a lot to do with improving their attendance by hundreds of thousands of people.
Harry's first stroke really effected his on-air moniker. If I had to pick one reason as to why I liked Harry Carey when he was with the Sox it would have been because of his brutal honesty. If a player f***ed up or half-assed a play, Harry would let everyone at home know how he felt about it. That much, at least, you had to respect about the man.
The day Harry Carey died, even though he was employed by the Cubs at the time, was a very sad day for ALL Chicago baseball fans.
