Songs in My Head
In addition to the BeeGees, I often have a variety of other songs that slip in and out of my head during the day. Neil Diamond songs, folk songs, hymns, The Wheels on the Bus, Somewhere Over the Rainbow. Etc.

Five minutes ago, this song, "What'll We Do with a Drunken Sailor?" came unbidden. Why? Why? My mom used to sing this. My favorite song she ever sang in her programs was "Hush Little Baby."
