[on her song Sea Creatures] Back then I only knew four or five chords on the guitar, so that's why it's so simplistic. I had a friend who was openly gay and being bullied and me and her were probably the only gay people in our year. There are so many different aspects of being 14 in that song like, you have that phase of 'Oh my God I want to get out of this town, I hate all of these people' and then the chorus is about people's ignorance and intolerance.
When I was really young, like five, I had severe dyslexia and they said I was never going to be able to write. The specialists said I should go to special schools but my parents wanted me to have the same chances as my two brothers. My little brother is also dyslexic and is on the autistic spectrum...
[describing herself] An Irish Leprechaun.
I had a hernia when I was two because I screamed so much.
[on becoming "obsessed" with song-writing at age 13] Until that point I had never been super-dedicated about anything and I never thought I was super-talented at anything either but then I started doing music and I got really into it.
I don't know what my thing is or why I'm so relaxed about getting tattoos - like, stupid things on me for ever - but there's nothing I regret. I wanted to get an Australian tattoo. Goon is a bag of [cheap] wine in Australia, and the moment I heard that word I laughed so hard. I don't even like wine.
He [my brother] smoked a shit-ton of grass while he was doing his A-levels and dropped out and did jobs, and left jobs. Now he's home, he's got a job and he's doing really good, but those songs were observations of what he was doing at the time and also my worries. [She felt guilty that while her music career was taking off, he was losing his way.] Kind of like: I'm doing this and it's going really well; you're doing that and I don't want to feel like you're angry at me because of that. [Her music allows her to express some of the things she finds difficult to talk to her family about.] In general, songs are how I talk to them about a lot of things.
It's weird when people ask deeply personal questions. To have part of your life analysed when you're still a teenager... well, I find it strange.
[on prurient interest in the fact she is lesbian] I find it very uncomfortable. I've had to develop techniques to wriggle out of questions I don't want to deal with. On occasion I'll say it straight out: 'I'm not answering that'.
[letter urging people in Ireland to legalise same-sex marriage] I have friends who have been kicked out of their homes [because they are gay]. Imagine how it must feel for a young person who's already going through a tough time, then on top of that to be told 'oh, your government is going to potentially bring in laws that protect and encourage the people that discriminate against you.' It's crazy.
I like Miley Cyrus, but prefer Taylor Swift because she's an incredible pop songwriter who sets an example by holding on to her own music rights - it's a good message to send to kids. But I am an even bigger fan of Kate Tempest, who is also my biggest supporter. She's amazing. She's my friend and she's incredible. She's an incredibly intelligent person. There have been loads of occasions this summer where we've bumped into each other at festivals and she's been like, 'how you doing? Is everything good?' She understands how busy I am and she's texted me and she's been like, 'how many hours sleep did you get?' I'll say 'I got two' and she'll reply: 'I got one'... She's a very cool person.
