ALUMNUS—Once a year, Dr. Demento returns to his alma mater, Reed College, to give a series of lectures on the weird and wild music that makes his radio show so iconic. Tonight's topic is "Grandpa's Pornography," or in other words, "Songs I Can't Play on the Dr. Demento Show"—so expect to hear some hilarious, bizarre, and outright dirty tunes. On Saturday he'll talk about the origins of blues, and Sunday he'll focus on all things Zappa. NL
