Hey, I'm Josh Barrow, your new host of Left, Right, and Center.

Every week join Rich Lowry, Bob Shear and Me for a contentious yet civilized debate of the week's big political stories,

You can find Left, Right, and Center on KCRW's iTunes page.

been here a few times. Oh, yeah. And of course, his new film, when he gets to play David Foster Wallace,

is the end of tour. Jason Siegel, thanks for being here.

Thanks, man.

In musical terms, the performance exists in that way for me, first and foremost.
