Folk singer Bob Haworth, or Bo Mooney as his cohorts knew him in the 1970s and 80s, took part in Vashon’s annual Sandiford Day Parades, a tradition that has since run its course. With a bow to those earlier years, former islander and member of two top folk-singing groups, The Brothers Four and The Kingston Trio, Haworth will return to Vashon to play a show, “Tales and Tunes from the Folk Era Music,” at 4 p.m. Sunday at the Vashon Theatre.

Haworth’s singing partner and guitarist, John Hollis, will join him on stage to perform the popular songs of the folk era from musicians like Woody Guthrie, The Weavers, Pete Seeger and his two former groups among others.

“The show is a retrospective of folk music,” Haworth said. “We like to get people to sing along — a bit like a hootenanny — and I tell some background stories about the artists over the years.”

Tickets are $25 for adults, $22 for students $20 for senior citizens and free for ages 12 and under and are sold at the theater’s box office or at vashontheatre.com.
