A book by Orton and Halliwell (published posthumously?) is http://astore.amazon.co.uk/joeortonl-21/images/041374910X Lord Cucumber and The Boy Hairdresser
Lord Cucumber is clearly another Time-Lord (or the name of the character in the mysteriously never filmed Channel 4 Dr-Who-With-The-Serial-Number-Filed-Off, something I never quite understood why Channel 4 didn't do, though I can't imagine Jeremy Isaacs being a fan of SF, somehow) and The Boy Hairdresser his companion.
And, of course, Cucumber was the show that Rusty had 'in development' before he returned to the UK because of his partner's brain tumour. http://www.digitalspy.co.uk/ustv/news/a328682/russell-t-davies-develops-showtime-drama-cucumber.html
