 We rang the doorbell, and a well-dressed man came to the door. And he said, can I help you out? I said, we want to see Sonny Boy. He said, this is Sonny Boy. I said, we want to hear you play your harmonica. He said, come on up. I'm proud to have you all. And I said, Sonny Boy, how do you make the harmonica say wow, wow, wow? He said, you have to choke it.
