Its hard to say there must be around 1500 maybe more,

I missed out on GC first time round and hoped to get them on general sale but they never released anymore, the thiefs at Ticketmaster just put them all up for auction on there own official sites. WTF. thats worst that they wankers on ebay.

I hate to say it i would be surprised if you get any on Friday, good luck though.

If your a member of backstage you will probably get one. they are going for $197.00 though and i think 1 membership card only allows you 1 ticket.
