I've known Mark Kermode for more years than I care to remember, and can still vividly recall late night discussions with him about — yes, you guessed it — The Exorcist in the days before the film was legally available on video in the UK. But even I learned stuff about the Good Doctor from this particular piece in today's Guardian. Not least the wax he uses on his quiff. Two, in fact. Red Dax and Sweet Georgia Brown.
