"Eve of Destruciton" from (sort of ) left field. I'm reading Mackenzie Phillips' memoir, so it's to be expected. But really, why not the "One Day at a Time" theme?.
Every morning — or just about — I wake up with some snatchlet of music in my head. Some days it may take well past lunch for the theme from "What's Happenin'?'" to work its way out and I figure why should I suffer alone?
