You should be able to use your fanclub membership. Just buy GA standing tickets and then queue up(very early!!) at the location that they give you on Backstage nearer the time. There are only a limited amount. This is how it worked last time and everyones seems to think it will be the same this time....don't know how many thought because of the "gold tickets" that let you into the pit.
Keep checking on Backstage for information.
