St. Louis’ Busch Stadium is anticipating the biggest crowd in its short history next July 17th. The Cardinals will be in Cincinnati that day. But the rock band U2 will be in the stadium. Concert promoters say the group will be performing on the largest concert stage with the largest tour production in history. Organizers expect 50,000 people at the stadium. The record crowd so far has been 46,800 for a Cubs game in July of 2008.
