Are there any bands that you hope to see while you are down at Worthy Farm?
"Yeah - really anybody I can see. It’s all so new for me. I’m not going with a fixed agenda. It’s massive for me to be on the same stage as the Rolling Stones a couple of hours before. I’ll be there for that and I’m keen to see Lianne La Havas, Alt-J, and Ben Howard too."
How do you unwind when you are on tour? How do you stop from going stir crazy?
"I haven’t worked that out yet. I’m trying to speak to other artists to gauge how to cope with it in different ways. I’ve been married for four years and I’m just getting used to being on the road without him. The new thing for me is that I’m always on show."
What are the fashion and beauty essentials you’ll be taking with you to Glastonbury?
"My makeup artist and stylist! My eyelashes are a staple for me and make me feel like a young lady [laughs]. Comfort is the main thing and I’ll make sure I’m warm too, that’s a major thing for me – I can’t be cold."
What’s coming up with you for the rest of the summer?
"It’s festival season for me. I’m excited about that. The bigger ones feel daunting but I’m doing a lot of jazz festivals in intimate venues, which fits my music a bit more. Although I like the challenge of playing the larger venues too."
Can you let us know if you’ll be playing any new music or cover songs for your Glasto show?
"I’m never going to give it away, otherwise people will get bored. Good try though."
