Mike Tyson says hello and greets you cheerfully by name. But almost before you can process the words, it’s hard not to be struck by That Voice. You know – that distinctive, high-pitched tone, whose softness seems to negate the trademark toughness behind it.

As the conversation unfolds, that voice is incredibly sweet, thoughtful, articulate and full of stories.

The whole time you’re thinking “This is Mike Tyson. The Mike Tyson, the so-called “Baddest Man On The Planet,” who is telling me stories about Vegas, boxing, serial killers and not grabbing butts. How unexpected and intriguing. Tell me more.

And that is basically the gist of “Mike Tyson: Undisputed Truth,” the former heavyweight champion’s one man Broadway show, which he brings this weekend to Seminole Casino Coconut Creek. Originally directed by Spike Lee and written by Tyson’s wife Kiki, it covers the ins and outs of his controversial life, confronting topics you might not expect, including his marriage to actress Robin Givens, his ear-biting episode in the ring with Evander Holyfield, and his rape conviction.

“Nothing is off limits,” he explains during a brief phone conversation. “I have other stuff I wanted people to know about, to know what happened, things you know about in the media and others you don’t know about. I love entertaining people.

“I’m not really talking about my life off-the-cuff like ‘I’m Mike Tyson,’ because if I did that within 10 minutes I’d be all over the place crying. In perspective, this is a guy talking about me, not really me, talking about me. I’m performing and being ‘Mike Tyson.’ But I have to say this – it happened. It’s all word-for-word what happened,” he says.

The show was born on a drive into Las Vegas with his wife, when the two passed a billboard advertising actor/writer Chazz Palminteri’s stage production of his show “A Bronx Tale,” which was made into a film that Kiki Tyson’s a big fan of.

“She loves the movie. I don’t know why young black girls between 30 and 35 are all crazy about that movie,” he says. “She wanted to see the play as well, and I said ‘I can do that stuff! Hey, baby, I can do that!”

Tyson’s evidence was past appearances in Europe and Asia where his meet-and-greets “are off-the-cuff. I interact with the crowd. I thought this would be more a creative experience. I wanted to totally be in the arts, so I just did it. It was successful, and I was ecstatic about it.”

Having acted before, most famously appearing as a Phil Collins-singing version of himself in “The Hangover,” Tyson says his only nerves about the Broadway date was “not entertaining the people enough. It’s an out-of-body kind of experience. (But) that’s what acting and fighting have in common – projecting an illusion and making it real.”

One of the stories Tyson tells in the show seems almost unreal, more like something you’d have written in an HBO series about boxing than someone’s actual life, but apparently it’s true. For a time the boxer trained in Phoenix, Arizona, and was one day approached by a man introducing himself as a sports writer. His presence wasn’t welcome by Tyson’s entourage.

“People started harassing him, and I was like ‘Don’t talk to him like that.’ I was in Muslim mode, in good faith mode, and it was a Muslim holiday – I don’t remember which one,” he says. “I said ‘Don’t talk to that man like that.’ I took my picture with him. A week later, the FBI came to see me.”

Uh-oh.

“I was thinking to myself ‘Did I grab somebody’s butt last night? No, the FBI wouldn’t be here if I did that. So that didn’t happen. I’m scared, because the FBI is talking to me, and I’ve been in trouble before,’” Tyson continues. “So they said ‘You had a guy in here before.’ And I said ‘I didn’t accidentally push him, did I? What did I do? Did I offend him?’

“And the agent says ‘No, he liked you. He just didn’t like the other guys he killed.’”

What?

“He was a serial killer. They had him on the computer saying ‘I’m a fan of Mike’s,’” Tyson says of former sports photographer Dale Hausner, who was, with a partner, indeed convicted of more than 80 drive-by shootings that resulted in eight deaths.

“I was like ‘Holy moley!’” Tyson says. “He was such a fragile guy, and weak.”

His inability to discern serial killers aside, Tyson says he’s thrilled to be embarking on a new career.

“I was always conscious that boxing was not something pervasive in my life. I wanted to entertain people. I like entertaining people. I want to do this for the rest of my life. I’m so fortunate and grateful. I have a great deal of gratitude for everything that happens. I’d like to be more humble. If you have to use the word ‘humble,’ it means you’re not humble at all.”

Tyson says that this person he appears to be now - the goofy guy air-drumming in a movie, the father and husband, and the Broadway star — is someone he’s evolved into.

“I work hard at it. If I believed any of my bio, whoever the hell that guy was, ‘The Baddest Man On The Planet,’ I’d lose everything,” he says, adding that he’s started a charity called Mike Tyson Cares, providing assistance to victims of domestic violence, and has called on his celebrity friends like “Hangover” co-star Bradley Cooper to assist in a fundraiser.

“I am very conscious of who I am today,” he says. “And I know how bad I want this.”
