After a close call at first base was argued by Cubs skipper Brian Harper, Dye, who was at the computer controls for the music clips used during the game, played the brief audio clip. It followed a controversial call by base umpire Ramon Hernandez in the top of the eighth inning. Seneca responded by ejecting Dye and ordering the stadium’s public-address sound system shut down for the rest of the game.

Seneca pointed to the press box and bellowed: “You’re gone! No more music!” Verbal announcements over the sound system for such things as batters coming to the plate or pitching changes also weren’t allowed.

I agree with the commentators on the above video: being ejected for playing “Three Blind Mice” over a PA is awesome.
