U2 first day ticket sales "extremely strong"

First-day sales were "extremely strong" for U2's July 17, 2011 concert at Busch Stadium, according to a rep from tour producer Live Nation.
Tickets went on sale Monday morning at livenation.com, at cardinals.com/U2 and by calling 314-345-9000. Busch Stadium box office sales began today.
"Limited quantities" are left, and it's advised that fans buy their tickets sooner rather than later.
A random check of online ticketing showed that only single tickets are available at the $32.50 and the $57.50 ticket levels.
