Barnes and Noble has a lot of old radio shows for sale. A couple of them have Joan Bennett as a guest on shows like Abbott & Costello and The Jack Benny Program. She also is on Duffy's Tavern, where she is wooed by Archie the manager, its available from mail order from Metacom (at least it was 10 years ago).
I would love to see an episode of her first television series, "Too Young to go Steady."
