My advice would be to hit up the box-office a couple of hours before showtime. There are always seats available....I have seen people (myself included) score front row on the day of the show - I'm sure other's online can share similar stories. I know it sounds like a bit of a risk, but I have seen it happen consistently in various cities that I'm confident in this approach. I'll be picking up my ticket on the day of teh show for the March 12th gig in Toronto.

Just my 2 cents.

CIao.
