I suppose we could speculate all we want as to why there weren't enough ticket sales. Sure it could be all the bad press he's gotten as of late, but in reality I bet those tickets have probably been on sale for a while now. People have had plenty of time to buy them and it could also be that he just wasn't selling well in that particular market.
If nothing else, it should be a wake up call to him that his name doesn't hold the value it once did to an entire market of people. If people cared the tix would have sold. Maybe Flyingmerpa is right, maybe this is the beginning of people finally showing him they've seen enough antics. I don't know.
Maybe it's all just a fluke. Just part of a perfect storm of poor promotion (IE: people not even being aware of the Wildabouts' existence), a bad market (as in maybe more of St. Louis' residents prefer country?), and bad press in recent months being the cherry on top. There could be way more I'm missing too. Like maybe he's even competing with another big show or event tomorrow. People can only be one place at a time ya know....
I don't know what the rock scene in St. Louis is like, in fact I don't even know too much about what the rock scene is like anymore here in Chicago for that matter. I'm so checked out of it all.... I know that in recent history there was a period of time in Chicago that we didn't even have a modern rock FM radio station to inform people of new mainstream rock bands and singles. Considering the state of rock music these days I guess it's not impossible that St. Louis could potentially be in that boat too. I'm sure someone from there could tell us if they have an FM station that plays modern rock music and if the Wildabouts get any airplay.
All in all, it is hard for me to believe that he'd sell enough tickets in places like Nebraska, Alabama, Louisiana, or South Carolina, but not St. Louis.
