Orange County is getting a huge helping of pop-punk star power in a very tiny place this week, thanks to Green Day. The chart-topping trio announced that it would be playing a "secret" (not anymore) show at the Tiki Bar in Costa Mesa on Thursday.

According to a midday press release, the venue will open at 8 p.m., and tickets will be available at the door for $20, cash only.

The release states that there will be no presales and a strict no-camera and no-cellphone policy. All proceeds will go to the Cystic Fibrosis Foundation, a national nonprofit dedicated to controlling and curing the disease and improving the quality of life for those with CF.

Green Day performs Thursday at the Tiki Bar, 1700 Placentia Ave., Costa Mesa. For more information, call (949) 270-6262 or visit http://www.tikibaroc.com.
