Sadly, there aren't any anymore.
My favorite talk show personality was Tom Snyder. He used to tell little anecdotes and then interview a very wide range of interesting guests on his show in the 1970's called "Tomorrow", and then in the 1990's he had a show "The Late Late Show with Tom Snyder". You can find episodes on YouTube. (Mr. Snyder has a standard American midwest accent)
Even though its an older program, you can learn a lot about American culture from it.
Some of my favorite guests were Harlan Ellison, Ray Bradbury, Ayn Rand John Lydon and Alfred Hitchcock
