Mine have been a slightly baffling selection just lately. First it was Tiger Feet. Then I caught myself singing Good King Wenceslas in the car, and couldn't get rid of it out of my head, then for several days it was 9 to 5 (for obvious reasons) and now, this afternoon, it has become A Nightingale Sang In Berkely Square, for no good reason I can think of.
Please tell me I'm not alone in this weirdness!
