It was always something that was there, I was lucky that way to have that push. It wasn't until I was 15 or 16 that I decided - I'd love to do this as a career. Before that, it was just a hobby. I got into musicals by chance. It was a bit weird.
-Since winning Britain's Got Talent, you've had the tour. How was that?
Oh, that was awesome. Most of the places, besides Glasgow and Edinburgh, I hadn't been to. It was good even just for that, to see the country and meet the people that appreciated what I was doing.
It was a completely different experience from singing in an empty pub or something like that. I actually can't wait to go touring again. I love performing live, you know? You get a buzz off it, especially when the crowd's on your side.
-In terms of playing live, you'll play your biggest show so far next month, at the Royal Variety Show. Are there any nerves ahead of that, or just excitement?
Well, a bit of both, but I'm definitely nervous! They're still here, I just move around the stage a lot more so I can control them. I think the shaky legs will definitely come out. It's the Queen, I can't not be nervous!
-Last year you auditioned for The X Factor. After getting to Boot Camp there, how was it moving to BGT and going all the way?
It was weird, it was a different experience. I thought about it right at the start, before I entered. I don't know if I could've gone back again, if that makes sense. For years I've tried things like demos and auditions, and never really got anywhere.
I got a bit of a buzz on The X Factor. I got through to the Boot Camp stages, and I enjoyed the process, but I think the Britain's Got Talent process was a little nicer.
X Factor, because they're trying to make you a pop star, it's more rigorous, longer hours.
Britain's Got Talent...you have to do a lot of work on it, but they're focusing on your talent as such, not trying to create something you're not. I suited that well, cos I didn't wanna be something I'm not.
-Both shows do come under criticism from people in the industry. Do you think the shows are still good platforms for up-coming artists?
To be honest, yeah. Well, obviously I'm biased, but my life has completely changed. I've had to do lot of hard work since the show - it's not easy, and you're not automatically the cat's pyjamas, going to sell hundreds of record.
You've gotta get the fans, gig and travel. It's definitely something that if a friend of mine asked if they should go on it, I'd say "Yeah, go for it," if they had what it takes.
-Before the shows you were a support worker for young people with disabilities. Did you ever imagine, at that stage, you'd get this platform?
No, not really. One of the guys I supported, he loves The X Factor and Britain's Got Talent, and he went on the tour last year. He came back from the tour, and he was telling me all about it.
He went: "You're better than most of them." I was like "Aye Robert, ok son [laughs]". "You should go for it" - "Ok, son." I thought...well, I'm not good enough for that.
One day, I had time off work, I'd just got a new house, I was doing it up. I was on the internet, and it came up on Facebook. I clicked on it, sent for an application and didn't think anything of it. I got an audition date, when I'd forgotten I signed up for it. Here we are!
-In terms of the work you did before, are you hoping to use your platform to raise awareness for charities and things like that?
Well, recently - in the last couple of months - I've been affiliating myself with Mencap. It's about getting young people with disabilities out into their communities and living their own life. I used my previous knowledge from my job to work to help.
It's something that goes unspoken at times. It's only really fairly new that people that I used to support would be able to get their own houses. I met a boy that I used to support the other day, his parents live in the same village I do.
He was dead chuffed, I had to apologise I hadn't seen him, cos I'd been travelling the country. He gets it. He did say that he missed me, I miss him too.
You form a bond - you spend more time with them than your own family, some weeks. It's a difficult thing to break away from, but that's why I wanted to stick with it.
It sounds dead corny, but I don't just wanna be the singer celebrity guy - I wanna do something with it. I wanna make it worth my while, and worthwhile to the guys that believe in me and got me where I am. I just wanna give something back.
