Get all the San Francisco Sound rock groups to have a concert in the park with volunteers passing the hat for donations.
Jefferson Airplane before Grace Slick.

I have fond memories of watching the Jefferson Airplane and other rock groups at free concerts in the GG Park Panhandle near Haight/Ashbury in the mid-1960s. This is before things got expensive a couple years later with paying $3.50 a ticket at Fillmore West, lol. At one free concert at GG Park, I got all the members of Grateful Dead to sign a record album cover. Those were good times, the city was clean and decent.
