Folk singer Peter Yarrow makes his second appearance in the Tucson area within a three-month period on Friday.

In November, Yarrow and Noel Paul Stookey, two-thirds of the famed trio Peter, Paul and Mary, performed a set at the Fox Tucson Theatre as part of an official tour.

This time around, Yarrow, 75, is playing a solo show at the Javarita Coffeehouse at the Good Shepherd United Church of Christ in Sahuarita as part of the church’s ongoing concert series.

The show is Yarrow’s only stop and offers him an opportunity that he wouldn’t have had otherwise.

As part of their visits, musicians are given a tour of the border region, courtesy of the Samaritans, the humanitarian aid program of the church.

Among other directives, Samaritan volunteers offer water, food and first aid to migrants found in the desert, working closely with the Border Patrol and other organizations.

A longtime advocate of social justice, Yarrow felt it was his responsibility to come down.

“If you want to really be an informed person and have an opinion that carries a certain kind of credibility and weight, you’ve got to go and see it for yourself,” he said from his home in New York City last week.

Yarrow’s performance at Javarita is nearly sold out. The Rev. Randy Mayer said around 75 tickets are being held for door purchase.

Yarrow said his set at Javarita will “be about caring and loving with a heavy bias toward songs of social justice.”

“This sort of work is the most satisfying kind of effort that I can be a part of,” he said.
