I too always wondered that until I found it on wikipedia click here : http://en.wikipedia.org/wiki/Sarah_Kennedy
and scroll down to the trivia section . I would never have guessed would you? :-D
Even that Wikipedia explanation doesn't make sense. I've been wanting to know what she means by it for years now. And I'd like to say that, while Ms.Kennedy has occasionally received some flak as a radio presenter, I think her show is excellent and absolutely perfect for that time of the day on Radio 2. I much prefer her to the egotistical Irishman who follows
I dont know if you were listening this morning but Sarah herself explained the meaning of S W's and it is the same as the one on the Wikipedia link I gave earlier. At least we all know the answer now.:-D
