I was playing my son some Supertramp. I don't know why Breakfast In America came back to my attention recently, but there it is. This evening, it came up because the family saw the Star Trek reboot, and when you think Spock, you should think of "The Logical Song".
But this brought to mind an element of my youth. I remember stopping by a friend's place, and his brother was there, long-haired and shirtless, airbrushing a mermaid on the side of his van, with Supertramp on the boom-box. At this moment, I cannot think of a more late-1970s moment than that. Can anyone one-up me?
