Florence Welch has given up drinking on tour.
Before, part of it was just the energy and it didn't really matter if you were hitting the notes. But now I can have both.
The Florence and the Machine singer thinks her voice sounds much better now she has cut out partying when on the road.
She said: "Some of the shows were completely unhinged. I'd be up a wall in an Irish theatre, in someone's box, doing a shot of whiskey with them and then back down to the stage.
"I can control my voice so much better now [I've given up drinking] and actually sing.
"Before, part of it was just the energy and it didn't really matter if you were hitting the notes. But now I can have both."
Despite giving up drinking on tour, Florence still enjoys partying and the feelings that being drunk give her.
She told Britain's Vogue magazine: "I love that kind of euphoria. I like that feeling of abandon. I like to dance. I like parties. I love shots. I love them."
