Well, I think the venue can hold over 1000 people... but this is Toronto we're talking about... a HUGE city. Opeth sold this particular venue out... Halford can and probably would do a hell of a lot more than them, especially with all the opening support he has. Tickets are $45. That's $45000 right there. Of course he has to pay the venue and other service charges I guess... but that's still quite a bit left over to pay the bands isn't it? The venue holds more than 1000, so there's more to be made. He said it would cost $60 if Testament were to come... but he chose not to have that happen. I think that was a huge mistake... pretty much anyone that wants or wanted to go to the concert was more than willing to pay well over $60 for it.
