There are two books by Pamela that are about Billy, "Billy" and "Bravemouth" that are biographical. I don't know if they are currently available but I have seen them in charity shops recently!

Pete McNab used to know him in his early years, but says that Billy could not remember him when he met him years later, the result of execess of alcohol and other substances at the time.

Truly a great comedian, his logical exploration of a subject leads him into the most amazing fantasies.
