The city of San Francisco has denied a permit for a ``Summer of Love 50th Anniversary'' concert, a free, outdoor event that was to be a focal point of citywide celebrations.
The June 4 concert in Golden Gate Park was expected to draw tens of thousands of people.
San Francisco's Recreation and Parks Department sent a letter this week to the event's promoter expressing deep concerns about safety and security for the concert due to his "numerous misrepresentations of material fact.''
Event promoter Boots Hughston says he met all the city's demands and is appealing the permit denial.
The concert was one of dozens of cultural events planned to mark the 1967 counterculture movement known as the Summer of Love.
The San Francisco Chronicle first reported the permit denial.
