I just recently started to listen to Cardinals games on a local FM station after years of listening on AM. The voices of the announcers definitely sound different, although still recognizable as Mike and Wayne.
But the thing that I've discovered is that Wayne Hagin on FM sounds a lot like Howard Sprague. Which to me is an improvement, as I 've never been fond of his voice or speaking style. Too plastic and contrived. It makes me appreciate the Moon Man much more, however, because those are two words never uttered in the same sentence with Mike Shannon.
