It is a bit unusual for grown men to cry, but Duck Dynasty's Willie Robertson could not help but be reduced to tears after watching the Duck Commander Musical, which opened recently at the Rio Casino and Hotel in Las Vegas.

Willie said that the musical tells the "American dream" and shows how their family built the Duck Dynasty empire into what it is today.

"It's emotional at times," Willie told FOX News. "I was crying watching it because you just think about if something were to happen differently, then none of this would have happened."

The musical even touched upon the scandal around Phil Robertson's anti-gay comments, which got him suspended from the show. It also earned them all a lot of flak, but the Robertson family firmly stood by one another.

"The media scrutiny and all this thing we went through, all that's played out in the musical," Willie said.

He is also very impressed with the stage actors and actresses involved and the way they were able to capture the unique Robertson family spirit. "Some of the characters, man, they've got us down," he said. "Not just the way they talk but all their mannerisms, they've done their job on getting us as lifelike as possible."

The Duck Commander Musical director Jeff Calhoun said that they tried to make the show as authentic as possible so that audiences would see a genuine rags-to-riches story.

"They really are living the American dream — and yes that's true for a lot of people but I'm not sure it's true for entire families by sticking together," Calhoun said.

Ginna Claire Mason, who plays Willie's wife Korie in the show added that they have a very special story to tell. "I think that anyone who has a family and has experienced the highs and lows of family life can first of all relate to this story," she said.
