Err it plays over the loud speakers at Wrigley. Yes, that's true. Also, I'm asking if WGN is the only station that still plays it after wins. Don't be an idiot. You're asking if the other stations selectively mute out the music being played in the stadium after a win? I think he's asking if the other networks play the stadium feed of Go Cubs Go after wins. Once the game ends and Len/JD stop talking they pipe in the stadium feed of the song so it sounds louder on TV
