The memory of Warren Hellman, the quirky San Francisco financier who founded the annual Hardly Strictly Bluegrass music festival and died in December, will be celebrated at a free musical event at Ocean Beach on Sunday.

Musicans and acts include Emmylou Harris, Boz Scaggs, John Doe, the Dry Branch Fire Squad and the Wronglers, the group with which Hellman often performed at Hardly Strictly.

Although the event is free and open to the public, space is limited at the venue — a fenced-off portion of the Ocean Beach parking lot opposite the Beach Chalet — and organizers are suggesting that people watch a live video stream of the show on the Hardly Strictly Bluegrass website.

The event runs from 11 a.m. to 6 p.m. Sunday, but gates will open at 8 a.m. Pets are not allowed, except for service animals. Food will be available for purchase. Alcohol is not allowed at Ocean Beach and will not be sold, and smoking is not allowed.

The performers:

• Poor Man’s Whiskey
• John Doe
• Kevin Welch, Kieran Kane & Fats Kaplin
• Dry Branch Fire Squad
• Steve Earle
• Buddy Miller
• The Wronglers with Jimmie Dale Gilmore
• Gillian Welch
• Boz Scaggs
• Old Crow Medicine Show
• Robert Earl Keen
• Emmylou Harris with special guest The Go to Hell Man Clan

The two stage areas are covered by tents, but the audience area is between the stages and not covered. Lawn chairs are allowed as long as they aren’t taller than about shoulder height, and umbrellas are not allowed.

Parking in the area is limited, but some San Francisco public schools will offer parking for a suggested donation of $25:

• Presidio Middle School – 29th Avenue between Geary Boulevard and Clement Street
• Francis Scott Key Elementary School – 42nd Avnue between Kirkham and Lawton streets
• Lafayette Elementary School – 4545 Anza St. at 36th Avenue

The Great Highway will be closed between Fulton Street and Lincoln Way, from just after midnight until 9 p.m. Sunday. John F. Kennedy Drive in Golden Gate Park will be closed between the intersection of South Fork Drive and the Great Highway, from just after midnight until 7 p.m.

The 18-46th Avenue and 5-Fulton bus lines will be affected by the Warren Hellman tribute celebration, with alternative stops on the 18 line temporarily substituting for the regular stops. Extra service will be provide on the 5-Fulton.

Organizers have provided an email address for questions about the event, questions@hardlystrictlybluegrass.com, but did not respond to an email from the Ocean Beach Bulletin.
