Nearly four decades after leaving millions of living rooms, Donny Most has something to say to Bradford — “I still got it.”

Most is perhaps best known for playing Ralph Malph on the hit television show “Happy Days” for seven seasons. He is bringing a different side of himself to perform at the Bromeley Family Theater at the University of Pittsburgh at Bradford at 7:30 p.m. May 12 — one where he sings.

“People are not aware of that side of me, which I am trying to change,” he told The Era. “That’s what I did before I got into acting.”

He grew up in Brooklyn, and performed in a musical review in nightclubs five years before joining “Happy Days.” When he turned to acting, he explained, “I put music aside and knew I would want to go back and do something with it.”

The music he likes — jazz, swing, Frank Sinatra, Bobby Darin — wasn’t popular at the time.

“In the 70s and 80s, when the show was so popular, that kind of music was looked upon as my parents’ and grandparents’ music,” Most said. “That genre of music was looked on as sort of passé.”

Since then, those oldies are becoming popular again.

“That music is back in favor in a big way, and the timing was right,” Most said, explaining why he began singing again. “About three years ago I decided to put together a live band and start performing. I recorded a CD of this kind of music, it was just released.”

It’s called D Most: Mostly Swinging.

“It came out incredibly well,” Most said. “It has some of the great standards, and it definitely swings.

“That’s what I’ve been doing and that’s what I will be doing at the Bromeley Theater, a bunch of songs I’ve recorded and others that I haven’t,” he said. “The audiences have been responding in a very enthusiastic way. It’s been egging me on to keep doing this. I get as high as a kite when I’m on stage with a great band.”

Most said audiences young and old seem to be enjoying his performances.

“This kind of music, the interesting thing I’ve found, when it’s done right, when you have great musicians and songs, it crosses all age ranges,” he said. “It’s very infectious.”

While reminiscing about happy times on “Happy Days,” Most said his fame from the iconic show can be a bit of a double-edged sword.

“I was never like the character I played,” Most said of Ralph Malph — a practical joker with girls on his mind. “I was more like Richie Cunningham,” the All-American teenager.

Yet after playing Ralph, Most said he tended to be typecast to a degree. “You are very closely associated with that character and it’s hard to shake. With time and perseverance, I was able to get more roles.”

He directed some theater and some independent films, acted in at least one independent film and had guest roles on shows like “Glee.”

Even more than 35 years after his departure from “Happy Days,” Most is still asked to say his famous catchphrase — “I still got it.”

“I find that rewarding to see it still being used,” Most said. “When I started hearing this phrase being used in the vernacular of our speech, that was incredibly rewarding.”

He gave a little back story on the origin of the one-liner. Director Jerry Paris would say it, and without telling anyone, Most decided to add it to his character’s lines.

“Nobody knew it was coming,” he said with a laugh. “It got a big reaction. When I hear it, or when people ask me to say it, I get a big kick out of it.”

He remembers his time on “Happy Days” with fondness, and acknowledges the tremendous opportunity it was for a young entertainer.

“It was a wonderful experience doing the show; they were incredible people I got to work with,” Most said.

And now he works with talented musicians, writers and arrangers of music, and is able to entertain audiences in a different way.

To audiences, Most would say, “If they love these great standards, this music that has stood the test of time, it will feel like that, but it’s not a museum piece. It’s pretty hip, too. Most of the things I sing are 70, 80 or 90 years old. I suspect a lot of them will be around for another 80 or 90 years — it’s the melodies, the wit, the sophistication, the poignancy.”

That may not be what audiences expect from the man behind Ralph Malph, but this trip back in time will bring happy days to the Bromeley Theater.

This show, at 7:30 p.m. May 12, is part of the Bradford Creative and Performing Arts Center’s season.
