I saw Motley Crue in June of last year at the same place I'm seeing them this year (just bought tickets today, $72 for pretty decent seats) and it was more or less almost full. I also saw a Vince Neil at a solo show in December and that was pretty full too though it was a tiny place, only held about 2,000 people or so. I did also see KISS in 2010 and that was almost sold out too, so I have no doubt this show is going to sell pretty nicely, at least where I live.
