I apologize if I too transgressed a boundary. I can see that an appearance on TV with Groucho Marx doesn't seem to fit in with the songs that were discussed in the thread earlier. However, the blues, the genre Gladys Bentley represents, in which gender boundaries were "interrogated," is itself over a hundred years old, and its roots in African American folk music go back much further, some would say to before the African diaspora. If that tradition is not of interest, I am sorry. At any rate, my breach of etiquette didn't cause anyone grief but myself.
