Live from David Douglas High School, it's an unscripted evening of tough questions for the mayoral candidates. We're calling it Mayoral Debate Club, co-sponsored by KATU.

Charlie Hales, Eileen Brady and Jefferson Smith better cram: No topic is too advanced. And it's free!

Where: David Douglas Performing Arts Center, 1400 SE 130th Ave.

When: 7 pm, Sunday, April 22.

Tickets: They're free. Seriously. Available at Willamette Week (2220 NW Quimby St.) and KATU (2153 NE Sandy Blvd.).
