Concert Help!

Well, I think there's been some confusion about who's playing where with the powers that be.

To start the story, I signed up for the GC mailing list, and in the latest email, it was sent out that they will play in rocketown in nashville on the fifth. It also said on the email that they teamed up with boys like girls for the tour. To confirm the concert, I went to this site, clicket on tour, and not only found that the concert didn't exist, but they were playing in navada, halfway across the US the same day. At this point I was a tad confused, and went over to ticketmaster. I found lots of tour dates for their tour, but not any on that date. Then I went to the Boys Like Girls site, and found them saying that they play in rocketown at that date.

From this I gather that there is a concert in rocketown that day during a tour where GC and BLG (lol) team up, but they question is: will GC be there, or just BLG (lol).
