^ Saw them last night, and during their second song, I went outside for more beer and smokes, and didn't go back into the venue til after they finished their set, which a lot of others also did.. Just didn't like their style of music at all, and thought they were a bad choice as an opening act for Gn'R..
As for that sitting down bit and not letting MUCC fans to the front, well I didn't see any of that last night (probably because I didn't stay), but can understand people doing that... If you want to see the opening act, you can just spend a few thousand yen and watch them in a small live house.. These tickets on the other hand were 12,000yen, and a lot of people lined up for hours to get good ticket numbers (or are fanclub members), and to give up your good spot at the front, so people can watch a regular band that they can see anytime, is just stupid..
