Here a question from a midterm that I gave to an Astronomy class (non-science majors) in Fall 2005. If I give this question again, it seems that I will soon have to modify it slightly. Who, before becoming famous as a rock guitarist, was a Ph.D. candidate in astrophysics? a) George Harrison. b) Jeff Healy. c) Eddie Van Halen. d) Slash. e) Brian May. http://entertainment.timesonline.co.uk/tol/arts_and_entertainment/music/article2062494.ece"
