If he were the obsessive music fan who narrates the LCD Soundsystem song “Losing My Edge,” Woodland Hills resident Howard Mordoh’s life might go like this:

“I was there at ‘The Last Waltz.’

“I was there when David Bowie debuted Ziggy Stardust at the Santa Monica Civic Auditorium.

“I was there at Neil Young’s Bridge School benefit: 1986, 1988, 1989…”

“I was there …”

Mordoh, although he has yet to narrate any songs, nevertheless is an obsessive music fan who has been attending concerts around Los Angeles for more than four decades. And he loves LCD Soundsystem, making a cameo in “Shut Up and Play the Hits,” the documentary on the band’s farewell concert.

Not only does Mordoh attend concerts — sometimes five or more a week, and often spending $1,000 per month on tickets — he’s usually on his feet, dancing, for the entire show.

His gray hair and beard, on a lean 5-foot-11 frame in constant motion, make him stand out in a sea of younger faces and bodies.

“It’s amazing I can still move. I’m 61,” Mordoh told me wryly. “I just never lost that energy inside me.”

He might have been the oldest fan at last weekend’s Hard Fest, an outdoor festival in downtown L.A. of electronic music acts.

“People want their picture taken with me,” Mordoh said. “One of my favorite comments is, ‘I want to be like you when I grow up.’ ”

He takes that to mean that they want to retain their youthful passion when they’re older. He certainly does.

“Music pretty much controls my life, I guess. It’s not my job. I worked in a medical lab for 20 years. But my passion is music,” Mordoh said.

For concertgoers around Southern California, Mordoh is a well-known unknown person, if that makes sense. He’s easily recognized, and yet who is he?

“People come up to me at shows and say, ‘I’ve seen you at shows before’ and just start talking to me. It’s a weird kind of celebrity,” Mordoh said.

“I never got this kind of attention when I was younger. It’s only when I turned gray, I guess.”

That and his dance moves are what caught the eye of me and my friends.

We saw him at the Fox Theater in Pomona in 2010 when LCD Soundsystem performed. In the balcony, where everyone was seated, Mordoh was on his feet, dancing solo, for song after song.

(One of my friends asked him to sit down because we couldn’t see. Mordoh’s hurt reaction: “We’re at a concert.”)

A month later, at the Hollywood Bowl, we saw him again, near the stage, dancing. Since then, my newsroom colleague Liset M?rquez has seen him three more times.

Last month, a friend and I watched “Shut Up and Play the Hits” at the Laemmle Claremont 5. At one point, for about two seconds, Mordoh was onscreen, dancing.

A half-dozen fans behind us gasped in recognition. They recognized him too.

I had to know: Who is this man?

In a hail-Mary move, I Googled “LCD Soundsystem dancing man” and the second result was an amateur video of Mordoh dancing by himself before the farewell concert. Is the Internet amazing or what?

The man wasn’t named, but I wrote a blog post incorporating the video and asking if anyone knew him. The LAObserved site picked up on that.

Days later, a man named Jeff Miller contacted me, saying he was a friend of the dancing man and that he’d sent the link to my blog post to him. And soon enough, I was meeting the dancing man himself in Century City at a KCRW-sponsored free concert with Band of Skulls and Raphael Saadiq.

Mordoh had never been interviewed, other than making the newspaper and TV news once in the 1970s by scoring front-row seats to a Paul McCartney concert after camping out in line for two days.

Miller had tried to interest Los Angeles magazine and The New York Times in stories on him but to no avail.

I’m so happy to beat them both, I don’t even care that Mordoh lives way out in Woodland Hills. I first saw him in Pomona and that’s good enough for me.

Said Miller: “He’s a fascinating character — lab scientist by day, music lover at night. I don’t think I’ve ever seen someone so passionate about their passion.”

Mordoh grew up in L.A. and learned to dance by mimicking moves on “American Bandstand” and “Soul Train” with his sister, who is now a professional musician.

His first concert was Iron Butterfly at Pasadena’s Rose Palace in 1968. He saw a lot of music greats: Led Zeppelin, Bowie, Queen, Todd Rundgren, Emerson Lake and Palmer, the Who.

“The new stuff doesn’t really compare,” Mordoh said.

In 44 years as a music fan, he’s never burned out or taken a break. If he ever felt as though he were losing his edge, the subject of the ironic LCD Soundsystem song cited earlier, it would have been in 2004.

But that year he attended his first Coachella festival in Indio and was exposed to dozens of younger bands.

His concert attendance picked up.

“It’s been five nights a week for the past two years. It’s accelerated since I started getting into newer bands,” Mordoh said.

Friends recommend bands, or he’ll hear about upcoming shows and investigate acts he doesn’t know. If he likes what he hears on Spotify, he’ll add the show to his calendar, which might include shows from Santa Barbara to Orange County to Pomona.

His tentative schedule for this past week: Nicki Minaj on Sunday, Aerosmith and Cheap Trick on Monday, Seal and Macy Gray on Tuesday, Of Monsters and Men on Wednesday, Die Antwoord on Thursday, Jack White on Friday, Liza Minnelli on Saturday (“from one extreme to another,” Mordoh joked) and the Red Hot Chili Peppers today.

While he likes records, he prefers live music.

“I lose myself in the music and just start dancing,” Mordoh said.

He tends to lean forward, moving his fists and torso up and down, but he’ll spin and snap his fingers and whatever else comes to mind.

“You just dance the way you dance,” Mordoh’s friend Ken Warren interjected.

“The older I get, the more I don’t care what anybody thinks,” Mordoh agreed.

As we spoke, in line outside the Annenberg Space for Photography’s “Who Shot Rock and Roll” exhibit, Mordoh experimented with a fast step he’d seen lately that he hadn’t quite absorbed.

“People say they like my energy, they like my moves. They can tell I’m having a good time. When they see me, it gets them out of their shell,” Mordoh said.

He doesn’t mind being the only one in motion. Others usually join him.

“Suddenly I’m surrounded by all these people dancing. That’s a great feeling. All this positive energy radiating from me.”

Bands appreciate him, he said, because he can get the rest of the audience moving.

“These newer bands, some of them recognize me from all the shows. ‘Give this guy some room — you’ve got to let him dance!’ ”

How does he do it? Power naps. A two-hour nap after work, he explained, and he could stay out until 2 a.m., get five hours’ sleep and feel fully rested.

“My parents used to win dance contests. I guess dancing was in my blood,” Mordoh said.

“My mother wanted me to go to dancing school, but my dad said, ‘No, it’s not a good living. You can’t do it when you get old. It’s bad on your knees.’ Maybe I’ve been trying to prove him wrong.”

His appearance in “Shut Up and Play the Hits” was a happy accident, as was attending the 2011 concert at Madison Square Garden, which fell during an already booked vacation to New York City.

He scored a ticket for the orchestra pit, which was where he was filmed, dancing.

“Shut Up” was his second movie cameo. Appropriately, the first was also a documentary about a band’s farewell concert: “The Last Waltz,” featuring The Band.

That 1977 show prompted Mordoh’s first trip to San Francisco. He said he can be seen in the movie holding an 8-millimeter camera, a hobby of his at the time.

Not dancing. That would have made the camera shake.

One reason Mordoh is seeing a lot of shows lately isn’t fun: He was laid off a few weeks ago. At his age, and with savings, he figures he’s done working, even if it happened earlier than he’d planned.

Until he sorts out what he wants to do, he’s seeing shows six or seven nights a week, eager to lose himself in the music.

Which prompts a question. After thousands of concerts, maybe tens of thousands, has he suffered any hearing loss?

“What?” Mordoh deadpanned. “Are you talking to me?”
