Singer also says she is still struggling with back injury in her live shows

Lykke Li has admitted she has never heard the Glee version of her recent single ‘I Follow Rivers’.

Speaking to NME ahead of her slot on The Park stage at the Worthy Farm event tonight (June 26), the singer replied to a question about what she thought of the musical show’s version of the song, by saying: “I haven’t heard that. No, not at all…”

She also revealed that she is still battling the pain of a slipped disc in her back during her live shows. The injury forced her to cancel UK tour dates earlier this year. Asked how she is coping with the back problem, she said: “So and so. I still get sick every other day. But I’m getting through. There’s no time for recovery as I hate cancelling dates. I won’t have much time for that.”

The Swede said the injury still affects her performance onstage and continues to hold her back in her live show. She added: “It means I can’t do everything I would normally do. I have to be more careful. Performing like this has been interesting, but I like overcoming problems.”

She also said that she hoped her performance at Glastonbury would be better than her 2008 debut there, which saw rain lash down as she played to an almost empty crowd. “Oh, I hope it will be better,” she said. “Last time it was like 11am and it was raining and there were like five people there so I can only hope for better…”
