Mark Madden of ESPN Radio 1250 was saying that the Station Square group (the one that supposedly is receiving the slots license from Gov Rendell to repay political favors) is not lining up a summer concert series at the fairly popular Chevrolet Amphitheatre. This is supposedly due to construction that would be happening for a new casino.
A quick check of the website shows that one show has been announced for April 22nd. Nothing else has been announced yet, but the site does say "Summer starts NOW". This will be worth keeping an eye on, for if the venue truly does hold off on concerts, which are incoming producing events, to begin construction on a casino when the license hasn't even been handed out, then we'll know the fix is in.
A quick look on www.archive.org at what the Chevy Amphitheatre site looked like back on Jan 30th, 2005 shows this.... hmm... if they don't have things going by the end of the month, I'm going to start to think that Mr. Madden is correct.
