It’s College World Series Time
Lambert Bartak (from Wikipedia):
Bartak performs in one of the few stadiums that still feature live music, as most stadiums have switched to prerecorded music. His image is often shown on the video screens at Rosenblatt, as well as on ESPN broadcasts of the games.
Bartak holds the dubious distinction of being the only organist to be ejected during a baseball game. During an Omaha Royals game on May 26, 1988, Royals catcher Larry Owen argued a call with home plate umpire Angel Hernandez. Manager Glenn Ezell joined the fray and during the argument, Bartak played the theme song from the Mickey Mouse Club. After Bartak played the spelling portion of the song “M-I-C-K-E-Y M-O-U-S-E”, another umpire Tony Maners motioned to the press box and ejected Bartak.
