Benny Green, the saxophonist and humourist, once told the story of when he was leaving Ronnie Scott's so late at night,
 
	that when he was on the bus home, the two ladies in the seat in front of him were two cleaners on their way to work.
 
	 
 
	He over heard one lady say to the other:   "Well, of course, Rex Harrison's not his real name",
 
	and the other replied:      "Rex Harrison isn't who's real name? "
 
	 
 
	This brought the programme to a halt.  I've never forgotten it.
