Actor Josh Radnor ("How I Met Your Mother"), has two new projects. Outside of being an actor, Radnor is also a musician, and he's recently released his new solo album, Eulogy: Volume I. Radnor is also about to star in a new play at The Public Theater, "The Ally," in which he plays a college professor named Asaf who is asked by students to sign a social justice manifesto, but the choice turns out to be much more politically complicated than Asaf first thought. "The Ally" is running at The Public starting on Thursday, and through March 10. Radnor joins for a Listening Party and to talk about the play.
