The people running Torchsong have given this official statement to hopefully clear up some things:
"Space Debris and Chez Lee Productions, promoters of Torchsong Chicago, are as disappointed as our attendees that both John Barrowman and Kai Owen are unable to attend this event. Although he cannot physically be present, John is working with us to make sure that the weekend is still an enjoyable one.
Present plans include:
-Peter Wingfield, of Highlander and Holby City fame, attending as a replacement guest
-John to still participate in interactive Q & As via SkyChat over the weekend
We're still sussing out a few other details but the event is still happening and we hope people will come and have a good time.

No word about potential refunds or future events, but I would guess that is an individual matter between attendees and the convention staff. According to the website, the chance for refunds ended on March 30th, but perhaps some exceptions will be made due to the sudden, disappointing turn of events. Unfortunately, running a convention means putting a fair amount of money and risk onto the table and because of that, even a partial refund could be impossible. Regardless, hopefully everyone who goes to the event will still have a fantastic time. I have my fingers crossed for all of you.
Thanks to Space Debris and Chez Lee Productions for this information.
