La Roux singer Elly Jackson refused to attend Glastonbury until she was performing at the event after missing out on tickets as a teenager.
Elly Jackson refused to go to Glastonbury unless she was playing.
The La Roux singer performs at the world-famous music event next week and says she is particularly excited because she refused to go as a spectator following a teenage row with her sister.
She explained: "I've never actually been because I made a pact with my sister when I was about 13, 14 - we'd both been on the phone for about four hours just ringing, ringing, ringing trying to get tickets.
"And I thought neither of us were going to get through, then just before the cut-off point she got like five tickets and I didn't get one and I was on the other phone and I was devastated, like so bummed.
"She didn't want to take her little sister with her to Glastonbury, do you know what I mean? I didn't get tickets, so I said, 'Fine, I'm not going until I'm playing'."
The 'Bulletproof' singer is planning to stay at the Somerset event for the full weekend as there are lots of other artists she wants to see perform.
She told BBC Newsbeat: "I'm looking forward to it, I'm just hoping it's not going to rain.
"This year my aims are to see Gossip, I'd really like to see Peaches obviously. I'd quite like to see Florence and the Machine live and White Lies, it'd be interesting to see what Lady GaGa does at Glastonbury too."
