Host Tim Boyum travels to New Hampshire to talk to documentary filmmaker Ken Burns about America turning 250 years old for this week's episode of Tying it Together.

Burns talks about his latest documentary on the American Revolution, what the founding documents mean to today's America, and what he thinks it means to be an American.

He tells Tim which historical figures he would most want to sit down with for dinner and what Mount Rushmore might look like if we chose again.

Host Tim Boyum travels to Tennessee to meet up with Lee Greenwood. As America celebrates 250 years, Greenwood tells us the incredible story behind his hit, "God Bless the USA."

From the inception on the tour bus to the stage with Ronald Reagan to an emotional story of singing it after 9/11, the song has defined his career.

What you don't know is that the song almost never made it. A limousine trip to a record label executive's house on Halloween changed the course of history.

On this week's episode, Martin Luther King III joins Tim for a wide-ranging and candid conversation about his dad, his death and what his dad would think about America at 250. King tells detailed stories about how his mom told the children their father was gone, the famous people who filled their home in the days after his death and how his dad worked hard to be a dad despite extensive travel.
