That's sad. I have a friend out here from San Bernardino who said he was at the Swing Auditorium for that date as a young kid. Unfortunately he died in a freakish auto accident a few years back. Sigh. He could have been interviewed.
I was at a record store in Temecula last month,and the owner's father was telling me that he went to that concert. I told him it was the first US concert for the Rolling Stones,and he was well aware of that.
