Your show's title was inspired by a review for your cameo in Norris & Parker's show last year, specifically where the reviewer thought you should be banished to. Do you usually react positively to criticism?
On that day we were feeling so terrible. But as soon as we read that review, we were backstage literally crying with laughter and had one of our best shows. That feeling of not being everyone's cup of tea is something I really embrace. Realising my act isn't for everyone has pretty much got me out of every rut I've encountered so far.

Your name is Hugh but you chose the stage name Huge. Why?
When I started in Aberdeen I did it in complete secrecy. I knew if I got sympathy credit I wouldn't get better. I performed as 'Huge', a nickname I had in an old circle of friends, so no one would ever find out. Now, it's a really useful way to write material. It's easier to write jokes for 'Huge', who has become more of a character than the exaggeration of my personality he used to be.

Wearing a full-sized keyboard for most of an hour, for most of a month, will inevitably cause you debilitating physical pain. How far are you prepared to go for a laugh?
Once people get used to the keyboard after the first ten minutes, they stop thinking it's weird. I don't think it's going that far; I'm not taking a shit on stage or anything. It also allows me to do loads of routines that I couldn't do if I were sitting behind a keyboard, so I'd rather have it than not. If a doctor told me that I might have serious lasting damage to my spine, I'd probably stop.

Where do your bleak worldview and deadpan delivery come from?
Honestly, it's the only way I can be funny. When people first see the keyboard when I walk out, it's normally too wacky for most at a comedy club. Delivering jokes deadpan whilst wearing it, is one of the only things that both balances the act and gives me the energy to actually wear the damn thing.

Is your material about child abandonment and abuse channelling your feelings over being sent to boarding school?
I've literally never thought about this and you're probably bang on the money. I don't go to therapy and this is why.
