   That is an excellent book - but be aware there is another book with a   
   very similar title which is a complete load of rubbish.   
      
   I was priviledged to have met Alan Blumlein's son, Simon, on several   
   occasions and chatted to him about his father.  Simon died about a year   
   ago; he was a lovely character with a similar sense of humour to his   
   dad.
