The mystery of Lewis Carroll - by Jenny Woolf 2010 ISBN 978-1-90598-68-6
Probably the best book to read about Lewis Carroll aka Charles Dodgson.
It clearly and authoritatively sets the record straight. The new information she uncovered about his finances and falling out with the Liddells is particularly interesting. It has probably been said that more nonsense has been written about Lewis Carroll than appears in his books - if not it should have been :-)
Pete and Dud - An Illustrated Biography by Alexander Games.
Conventional wisdom is that Peter Cook and Dudley Moore were very funny in the 1960's and never really reached those heights again. This book tries to argue that perhaps some of the Derek and Clive stuff was very funny - but misses the point that conventional wisdom could be right and it doesn't really matter. Where conventional wisdom might be wrong is in arguing that Peter Cook in particular wasted his comic potential, whereas anyone who achieved so much is surely allowed a bit of slack !
The book is a good attempt to paint a warm and human picture of two complex and very different individuals.
Further Adventures of a Grumpy Old Rock Star by Rick Wakeman - This book has me laughing out loud with genuinely funny stories from his life. True I don't think I've ever listened to any of his music, but as when the old lady asked him if he had made any discs, he replied yes, 136, she said "Have you sold all of them yet". Full of self-depreciating humour like the time he did a signing in Woolworth's and no-one turned up !
