I drove my 1953 MGTD, 2 nights in a row in August 1965, to see the Beatles at Hollywood Bowl. No tickets.
The first night we were turned back by security. The 2nd night, we were told to sit along the hills, which we did.
At the time, it was just the sort of thing kids just out of high schooll did. Who would have thought we would be looking back 54 years later at how cool it was.
