This biography doesn't work. I spent some considerable time trying to work out the reason and, the best with which I can come up, follows;
Brian Johnston was one of those chaps who were bigger than his achievements. To hear him broadcast was to discover a lost but much loved uncle. This book suffers from being rather too rosy a picture but, at the same time, if it had gainsaid the legend, I shouldn't have enjoyed that!
The second problem with this work is linked to the first, the author was not aquainted with Johnston and so, relies heavily upon other people's stories. They too did not wish to 'dish the dirt' upon a national institution and so, there was little but a eulogy and very little that one did not know before starting the book.
Having bben so negative, it was still pleasant to revel in the remembered joy of a Brian Johnston commentary. ( )
