It's a charity concert next week. It is hosted by Katy but will feature some other singers as well. One way to get tickets was through a contest held by PopChips over the summer. You could get game pieces in specially marked bags of Katy's Kettle Corn, but all summer I could never find one of those bags. And I checked many stores. Another way to get a game piece was to send a SASE to PopChips. I tried many times but did not win. I believe 25 prizes were given out. Then tickets went on sale--first to CitiCard members who could buy a VIP package that included a pre-show Q&A with Katy. Then the tickets went on sale to the general public. Hope this helps.
