Watch Clint Eastwood Sing in a Movie Musical [VIDEO]

We've been talking musicals all week, when a caller reached out to remind us of the 1969 classic Paint Your Wagon. Clint Eastwood! Lee Marvin! In a musical? That's right. Granted, it's a western musical where these tough guys are still in tough roles. But it's still a shock when we first hear it. Dirty Harry and the leader of the Dirty Dozen, singing? Oh yes. It's a beautiful thing.
