When asked about touring, Brown says: "It's still my favourite thing to do. Everything – from the writing of the show to the actual performing and touring – is a huge delight."
"Andy Nyman was my co-writer for many years of television shows. Now we've joined forces again, we're very eager to make this show feel different. There was something of a template we followed with all the shows, which worked very well.
"It's rather exciting and scary leaving that behind. This one should certainly have a different tone, and will mix things up a bit for those who have seen the others on TV or live.
"I just try to find what's interesting to me, while of course making sure I don't repeat ideas from previous shows. This year as we've tried to change the feel of the show, that has brought its own concerns – how much should you change for the sake of changing? Why fix what wasn't broken? "
"But these are all part of the creative drive: complacency doesn't help anyone."
Brown has attracted his fair share of controversy, but this doesn't phase him. "It's nice that the shows are very well received," says Brown. "I'm used to them also provoking their share of negative or sceptical reactions from some quarters – anything from 'it's all fake' to 'it's irresponsible and he shouldn't be doing it'.
"I see it as an inevitable kind of tax I pay for doing something that might be very ambitious. It's only saddening when I see people – usually on Twitter – wrongly dismissing something that happened for real as fake and feeling insulted rather than letting themselves enjoy it. But whaddyagonnado… you could go mad trying to please everyone."
