CHICAGO – Maybe it was race driver Jeff Gordon’s shout out to the fans at “Wrigley Stadium.” Or Ozzy Osbourne, who decided the lyrics of “Take Me Out to The Ball Game” were not nearly as interesting as the mostly unintelligible words he’d picked out for himself. Or perhaps it was actress Denise Richards, who brought along a little cheat sheet in case she forgot the words.

Whatever the reason, the Cubs have decided to make the broadcast booth at Wrigley Field, and more importantly, the microphone, off limits to the likes of Vanna White, Erik Estrada and Mickey Rooney. Marion Ross apparently will be the last member of the “Happy Days” cast to sing during the seventh-inning stretch. No more Kid Rock, who, as the story goes, knew it was customary to say something at the end of the song, but went with “Let’s get some lunch!” instead of the more traditional “Let’s get some runs.”

“I think the last couple of years we had gotten away to a couple of people who weren’t tied to Chicago,” said Jim Oboikowitch, the Cubs in-game programming director in what might be a bit of understatement after more than a decade of Peter Frampton, David Cassidy, Barbara Eden and Frank Sinatra (Junior) leading the Wrigley faithful in song.
