It hit me in the shower: the chorus from "Mr. Sellack," by the Roches. Now I have to buy yet another copy of that CD, play it twice, then lose it or lend it again.
Just for fun, "The Troubles."
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?
