A person's musical taste can reveal a lot, so imagine how eagerly the Diary waited to hear the tracks chosen by Alison Richard, Cambridge University's vice-chancellor, on Desert Island Discs this week on Radio 4.

But could her staff have anticipated two songs from her early student protest days - the Rolling Stones' Sympathy for the Devil and Creedence Clearwater Revival's Lookin' out My Backdoor?
