PORT TOWNSEND — The PT Songlines Choir’s Winter Participatory Concert is set for 7 p.m. Saturday.

The concert will be in the Cotton Building, 607 Water St., Port Townsend.

Admission will be by a suggested donation of $15-$20.

At PT Songlines concerts, the audience is invited to both listen and to join the choir in singing easy-to-learn songs, organizers said.

All proceeds will be donated to Jefferson County Immigrant Rights Advocates, which provides immigrants access to legal services, standing witnesses, family support, community education and advocacy for local, state and national issues.

PT Songlines is co-directed by Laurence Cole and Gretchen Sleicher.

The spring singing season will begin Feb. 11.
