Yet, the three brothers who are supporting the tour and gearing up for movie roles are no secret to tweens. The Jonas Brothers was the featured act at the State Fair of Texas October 9 and made clear their time is now.

An estimated 20,000 fans showed up for a 3 p.m. show, making it the third-largest concert in the fair’s history, topped only by Garth Brooks in 1990 and Selena in 1994, who both drew crowds of about 30,000, according to the Dallas Morning News.

The concert was described as “sardines in a can” and 200 were treated for heat exhaustion.
