Hayden is one of over 100 celebrity contributors to a new book celebrating Doctor Who.
Behind the Sofa was compiled by author Steve Berry in aid of Alzheimer’s Research UK, in memory of his mother, Janet, and is beautifully illustrated by Ben Morris.
There are also contributions from Rhys Thomas, Charlie Brooker, Jonathan Ross, Tracy Ann Oberman, Toyah Willcox, Stephen Merchant, Nicola Bryant, Charlie Higson and Paul Whitehouse.
The book will be published in September, but you can get a limited first edition by pre-ordering one now. The hardback version is £14.99 and the e-book a very reasonable £4.99. There are also special packages available for those with a bit more spare cash.
