On March 20, 1964, legendary American comedian and harpist Harpo Marx joined the Riverside Symphony on stage at a benefit for the Southern California organization. By then, the comic had been in semi-retirement, and after a series of heart attacks in 1961, he was told to stop working altogether. But to a lifelong performer, nothing compared to the feeling of being on stage. Benefit shows, he slyly argued, were not technically work, since he wasn’t getting paid. For the next few years, Marx’s wife and doctors grudgingly went along with the pitch. 

Harpo Speaks! The Riverside Symphony Concert, out June 5 from Ramseur Records, captures a considerably remarkable, one-of-a-kind performance: The silent Marx Brother, the one whose trademark persona led many audiences to believe he was actually mute, spoke.

As Harpo Marx’s first, and last—recorded just six months before his death—live album, Harpo Speaks! places listeners in the room, immersed in the swell of the Riverside Orchestra as Marx performs alongside the symphony and leads them in a narration of Peter and the Wolf. In another unusual move for Marx, he allowed the recording of the show for posterity, though the tapes seemingly disappeared after his death.

Harpo Speaks! is the result of heroic archival work. Recently discovered by longtime Marx Brother archivist John Tefteller, he and Marx biographer and expert Robert Bader set out to restore the long lost recording. “The fact that we have a recording is a miracle,” says Bader. “It was not the most professionally recorded thing. It was very haphazard. The work that was done to rehabilitate it is stunning. It’s as if you’ve found something covered with layers of mold and dirt, got it all cleaned off, and now are able to see something brand new underneath it.”

Across the recording’s near-43 minute runtime, Marx, alongside the Riverside Symphony, takes the cheering audience through the delightfully lighthearted “Toy Symphony” and carries them into the softly romantic “Moon Medley,” (a medley of “Fly Me to the Moon” and “How High the Moon,” arranged by his son Bill, alongside his own composition, “Moon Tune”) and a rare instrumental performance of his composition “Guardian Angels.”

And then the concert’s true highlight: the near 22-minute long riveting narration of Peter and the Wolf. For the first time, Harpo reveals his voice: deep, yet soft-spoken, refined, yet still retaining the slightest hint of his New York City origin. And, in speaking, he entertained, getting laughs not just for his physical gags, but for the storytelling itself: the dramatic inflections in moments of suspense, the arch mischievousness, and tongue-in-cheek references to Goldwater, Rockefeller, and Nixon. 

To listen to Harpo Speaks! is to experience a brush with magic, astonished and captivated by the talent before you, and filled with wonder and gratitude for the privilege of witnessing it, whether in 1964 or today. Says Marx’s son, Bill: “To have this recording be released and let people hear it is an honor. Dad didn’t really want people to know what he sounded like because it would have destroyed the character of Harpo that he created. But I think, now, he would accept this graciously and gratefully because it goes beyond just seeing a guy being funny. It goes to the heart of what life is about: Doing what you love and doing it the best you can.”
