Junction 15 of the M25 may not be the first place that comes to mind when you think of escapism, but for me as a child in the late 1980s, joining the M4 was crossing a watershed. We visited my grandparents in Wales every summer, and not only did leaving the London Orbital mean we were properly on our way, it was also the point at which I was allowed to ask for music to be played. I always asked for The Best of the Beach Boys. (No one objected: my father had loved the Beach Boys since the 1960s, even before his older brother moved to the US.) Their songs weren’t just the soundtrack to a car journey to Wales, but a gateway to an America of the mind.
