By connecting with an old friend, I've had songs from my high school years playing in my mind. That isn't hard, of course, because I keep oldies going on my Ipod quite often. But besides the obvious -- CCR, the Eagles, America, -- it's been Loggins and Messina, Jim Croce, Dr. Hook and the Medicine Show, Bread, the Carpenters, John Denver and Elton John. Elton John? the Carpenters? Where's that coming from? Music has this amazing ability to stick in the memory when all other stuff starts to leak out.
