It's amazing what you can do when you put your mind to it!
Two nights ago (late - in the black of the night) I heard this bumper music on either Lars Larson or another A.M. host.
I only had one chord stuck in my head and a memory that the singer's voice had a modicum of nasality and came from the back of the larynx. I went through Joe Jackson's greatest hits, ABC, and finally ended up with sweet serendipity on my third try, Spandau Ballet. Incidentally, they've reunited and are on tour!
