With sales where they presently are for Louisville, the band easily stands to make around $3-million, if not more, just from tickets (i.e., not including merchandise).
As I've said, tickets are around 90% soldout, with the show being a few months out. There's no possible way that this can be construed as a negative, and especially as if the band is somehow "not doing well".
Case in point, stadium shows in Tampa have consistently failed to sell 100% of tickets, yet they still book there on practically every tour. Same with other mega acts: I saw Springsteen in Pittsburgh last September, and there were about 3,000 unsold tickets. They still made close to $2 million on ticket sales, played for almost 4 hours, and I guarantee you that he'll be back, either w his own band or to play w Joe Grueshecky again. It's not like he'll be thinking, "You know, we only sold 16,000 out of 19,000 tickets, so, despite making over $1.5 million, that night was a failure. Let's not play there again."
Gimme a break.
I do get not wanting to travel crazy far for a show, though. U2 normally plays Atlanta, which is close to Birmingham, but I think that they're renovating the Georgia Dome right now? I know that the new baseball stadium will be up-and-running by then, but they haven't played baseball stadiums with any consistency over the years (Busch and Angels Stadium on the 360° tour is really all that springs to mind).
