This season, WGN's website is running blog posts discussing events that have happened on that day at Wrigley. Here is the description of the special:
Narrated by WGN Radio’s Steve Cochran and featuring custom drawings by cartoonist Drew Litton, the magic moments and memories of a century of baseball at Clark and Addison are told via interviews with over 60 different people, including Hall of Famers Ernie Banks, Billy Williams, Fergie Jenkins, Ron Santo, Andre Dawson, Greg Maddux and Ryne Sandberg; as well as Kerry Wood, Rick Monday, Rick Sutcliffe, and Derrek Lee. Visiting greats such as Hank Aaron, Vin Scully, Mike Schmidt, Albert Pujols, Bob Uecker and Paul Konerko will add their thoughts as well. Other segments include Mike Ditka and Gale Sayers on playing for the Chicago Bears at Wrigley, fun and crazy moments at the park described by Harry Caray and Jack Brickhouse, and an in-depth look at some of Wrigley’s greatest games.Here is a YouTube clip of the intro to the special.
WGN has a special bond with this blog simply because a majority of our color content has come from surviving WGN specials. I have contacted WGN in the past and they have told me on a few occasions that a cache of classic broadcasts aren't hidden away somewhere. What we have seen is what exists. I don't know that to be 100% true, as things can be mislabeled or misplaced but I would imagine if there is something new, we might see it on this weekend's show.
