Tonight on Peersborg and Unsensored.

He's one of the smartest and richest men in music history.

Kiss legend, Jean Simmons, gives me his lessons from an extraordinary life.

We'll talk money, power, showbiz, scandal, politics and love.

He's had it all.

Strap in, it's going to be a crazy uncensored night.

From the news building in London, this is Piers Morgan Uncensored.

Well, good evening. Welcome to a special edition of Piers Morgan Uncensored.

Last time my guest was here a few weeks ago, I left wanting a lot more. I thought, why aren't we doing a whole hour with this guy? So I asked him. He couldn't understand why we went either. So he's agreed, and he's back for the whole hour tonight. A true living legend of rock one-on-one.

Gene Simmons is rock and roll royalty. Kiss have more gold-certified records than any other band on the planet, selling 75 million records in half a century of touring and two months.

From rags to riches, Jean has turned in beats into a business empire.

He's got the longest tongue in rock,

and one of the sharpest tongues in politics.

They called him Dr. Love, the demon.

The God of Thunder is quite possibly the world's smartest ever rock star.

And tonight, Gene Simmons is uncensored.

Well, Gene Simmons, Joyce been, I said, Gene,

I've actually got a stinking cold.

And so my first question was going to be,

when you're a singer, what do you do when you get a stinking cold

and you're on tour?

I never claim to be a singer.
