Here's at least part, if not all, of a 1975 radio interview with Moe done by Brad Lemack. The video is bookended by Stooge clips, but the not-too-long interview is in the middle. Some of the stuff we've heard in other interviews, but find out what Moe thought of Seasme Street and if he ever watched his old films.
