Instead, thanks to “Shut Up & Sing” — a new documentary about the group’s foray into politics — the Chicks will likely be famous for flying their self-proclaimed victim banner once again.

The documentary accurately and intimately portrays the Chicks’ tumultuous battle with angry Americans since lead singer Natalie Maines proclaimed from a London stage that she was ashamed that President George W. Bush hailed from her home state of Texas.
