Unless there's a last minute cancellation or some problems, this show IS happening.
Update: No it isn't!
"I spoke to the people at Soundstage and according to them tickets are only available for this if you win them on the radio from WXRT or if you get a personal invitation from Mastercard (must be for big spenders). Or you can bid on them on Mastercard's auctions with your advantage points. No tix will be for sale to the public. Apparently I should have bought those ebay tix!"
