Peter Yarrow, a member of the legendary 1960s folk trio Peter, Paul and Mary, has passed away at the age of 86.

Yarrow died on Tuesday following a four-year battle with bladder cancer, his publicist confirmed to The Guardian.

In a heartfelt statement, his daughter Bethany Yarrow said, “Our fearless dragon is tired and has entered the final chapter of his magnificent life. While the world knows Peter Yarrow as an iconic folk activist, those of us who loved him knew the generous, creative, passionate, playful, and wise soul behind the legend—just as his lyrics reflect.”

Prior to his passing, Yarrow’s children created a “living tribute” website, inviting fans and friends to share messages, photos, and videos in his honor.

The site also features updates from Yarrow’s family, shared during his final days. In the latest post, dated January 3, Bethany reflected on their Hanukkah celebration, describing her father’s enduring spirit.

“Peter is physically very weak, but his spirit remains strong, and his light grows brighter each day,” she wrote. “We won’t let the light go out! We love you, Peter!”

Yarrow, along with Paul Stookey and Mary Travers, helped form one of the most iconic folk groups in music history, known for their timeless songs and commitment to social activism.
