Jim O'Brien

I was a child and a teenager in an era that was suffused with optimism. I know it’s a cliche to talk about the Swinging Sixties but it was a good time to be alive.

The Beatles, rock ’n’ roll, the explosion in youth culture and a general growth in material well-being meant more and more people never had it so good. Everything seemed to be getting better every week.
