Who would you like to see playing you in the movie about your life? Who do you think the casting people would choose? Well, I’ve just worked with two legendary Scottish actors, Sam Heughan and Richard Rankin, who were absolutely brilliant. I learned so much from them both. Obviously, most people are going to say Johnny Depp or Brad Pitt but I’d want someone with a great sense of humour, so Bob Mortimer will be my choice. Comic genius.

What’s the punchline to your favourite joke? ‘To cover their butt quacks’.

If you were to return in a future life as an animal, what would it be? An elephant. I was fortunate enough to spend some time with elephants in Thailand a couple of years ago, although being a panda looks like it would also be a lot of fun.

If you were playing in an escape room, name two other people (well-known or otherwise) you’d recruit to help you get out? My go-to in any crisis is always my manager Dave. He’d be sure to broker us a way out! Second, I’d pick Stephen Fry. He’s intelligent enough to get me out of any room.

When was the last time you were mistaken for someone else and what were the circumstances? Someone did think I was Lewis Capaldi once. I completely went along with it.

What’s the best cover version ever? I absolutely love the Hendrix version of Bob Dylan’s ‘All Along The Watchtower’. In actual fact, we will be paying homage to it in our December shows and rehearsed it today.

Whose speaking voice soothes your ears? James Earl Jones, closely followed by Snoop Dogg.

Tell us something you wish you had discovered sooner in life? Sobriety and the benefits that come with it. Boring, I know, but I’ve become a passionate advocate for mental-health charities, and I had never really realised how much making the right choices helps with my own mental health, and how much of a massive impact alcohol has on it for me personally.

Describe your perfect Saturday evening? These days, it’s a Chinese takeaway and a great movie. A far cry from the days when I’d be out all night, and then in a casino until they flung me out! Although we do a lot of gigs on Saturday nights, so I suppose my perfect Saturday night is a sold-out Barrowlands.

If you were a ghost, who would you haunt? That’s an easy one: Margaret Thatcher, all day and all night, 365 days a year.

If you could relive any day of your life, which one would it be? That’s a hard one but I’m going to say bathing with elephants in Thailand, which I hope I can do again next year.

What’s your earliest recollection of winning something? Before I was writing songs, I was a very keen footballer and won a few trophies, which was great. Sadly though, when I was a kid, I was devastated to find out that a few of my mates had got trials with big clubs and I hadn’t. A few weeks later I told my granny about it, and she said ‘aye son, they phoned, but I told them you already had a club’. True story!

Did you have a nickname at school that you were ok with? No. I’ll just leave it at that…

If you were to start a tribute act to a band or singer, who would it be in tribute to? I think it would have to be Bowie, who is one of my favourite artists of all time. But I would never try to impersonate him; it’s just too hard to recreate his genius.  

When were you most recently astonished by something? Last year my manager called to tell me we had sold out Edinburgh’s Usher Hall in 90 seconds. I still actually find it very hard to believe! Especially given that three years ago I couldn’t sell 50 tickets.

What tune do you find it impossible not to get up and dance to, whether in public or private? We’ve done quite a few dates this year with Sophie Ellis-Bextor, who is genuinely the most lovely person; so I’ll say ‘Murder On The Dancefloor’. A brilliant pop song, written by one of my favourite songwriters.

Which famous person would be your ideal holiday companion? I quite fancy going on holiday with Elton: imagine how amazing the hotels would be?! Fresh flowers everywhere; sounds good to me. Or Bruce Springsteen. I’d spend the whole holiday grilling him about his writing process until he kicked me out.

As an adult, what has a child said to you that made a powerful impact? My manager and I do as much charity work as we can, so I’ve had the privilege of spending a lot of time with kids who are terminally ill, and some of the insights I have had from those kids far outweigh anything any adult has ever said to me.

Tell us one thing about yourself that would surprise people? I am absolutely petrified of wasps. My manager nearly crashed a bus once because a wasp got in the window and I freaked out.

When did you last cry? I cried when we made the video for my current single ‘Something In My Eye’. That’s the one with Richard Rankin and Sam Heughan. It’s a song about mental health to support the charity Mikeysline, and it was a hugely emotional day.

What’s the most hi-tech item in your home? I’m an absolute technophobe. My phone is the highest tech thing I have, and I can barely work that.

What’s a skill you’d love to learn but never got round to? I would absolutely love to have learned properly about production, like the technical aspect of it, as sometimes it’s very hard to explain to people what is in your head when it comes to recording and songwriting.

By decree of your local council, you’ve been ordered to destroy one room in your house and all of its contents. Which room do you choose? Awww, I absolutely love my house, so that’s a hard one. I’d go for my living room as I’m happy to spend most of my spare time in my bedroom watching bad TV.

If you were selected as the next 007, where would you pick as your first luxury destination for espionage? Definitely Thailand: my favourite place in the world. Then the Maldives.
