Why was 'Lee Evans: So what now?' cancelled?

After some digging around I found this interview with Lee where he says.

‘I was writing the scripts and then I’d get on set and I’d be given a script with someone else’s name on it. It was like being punched in the stomach and you’d have to start performing feeling like that. ‘The show turned into something completely different from what I intended it to be. It was as if they didn’t trust me, as if they didn’t think I was good enough a writer, but it didn’t work. I had to walk away from doing any more series. I just went home.’

So it was Lee himself.
