POP/ROCK - Oct. 6, 1989

It will be just like the old days, sort of, when the Jefferson Airplane plays a free concert Saturday in San Francisco’s Golden Gate Park, with the Grateful Dead’s Bob Weir as opening act. Admission will be one can of food for the San Francisco Food Bank. But demonstrating how things have changed in the 20 years since free concerts in the park were the norm there, a radio station has had to take out a $1-million insurance policy to cover the event.
