Keith Baxter on Mrs. Warren's Profession at the Shakespeare Theatre Company - YouTube. A very good interview commentary regarding the play, the actors, and modern issues with performing this play (such as: the audience liking Kitty Warren more than Vivie Warren!)
Mrs. Warren's Profession - YouTube. This is a bit of the play performed in a theater. It is the scene where Vivie learns the truth about her mother. The girl that plays Vivie is not very good, but Mrs. Warren is portrayed pretty well.
