On the first Saturday of every month (next one is coming up on Jan. 7th), the National Park Service hosts a free Chantey Sing at the Hyde Street Pier from 8-11 p.m.
This public sing-along of chanteys and sailor songs is held aboard a historic ship at the San Francisco Maritime National Historical Park. The facility is wheelchair accessible.
Wear warm clothing and bring a mug for hot cider. Reservations is required as there is limited seating. To RSVP, call (415) 561-7171 or e-mail firstname.lastname@example.org.
