Whenever he can, Alan Fraser likes to play his saxaphone. But at other times he's been an enthusiastic magician, a jug band washboard strummer, a stand-up comedian, a bit of a singer, a composer/bandleader, and the owner of his very own jazz club. There were some other jobs too, but they were all about money - and not much fun at all. He lives in Oxfordshire and is married with two children.
