The event, which is thought to be the first of its kind on a Major League stage, is scheduled for April 17 with the White Sox in town -- exactly 50 years after the A's inaugural game at the Coliseum.
"We were really just looking to do something special on the actual anniversary date, and it's really a gift to the community, a gift to our fan base to say thank you for 50 amazing years," A's COO Chris Giles said. "We're really excited. It'll be a fun day."
Season-ticket holders are guaranteed admission, as are fans who attended the first A's game at the Coliseum.
