Elly Jackson explains Glastonbury boycott

Elly Jackson has explained why she decided never go to Glastonbury until she played there last year as an artist.

The La Roux singer previously revealed that she had "made a pact" with her sister not to visit the annual music festival at Worthy Farm, Pilton.

Jackson told Paul Morley for The Guardian: "My sister went every year since when she was about 14. She went to a school called Pimlico in central London which was very left wing and arty and I went there as well

"Obviously they didn't want all the students to go to Glastonbury - and they actually protested and rallied against it and the whole year went, regardless of the fact that they were supposed to be in school on the Friday and the Monday."

She continued: "She used to tell me these stories. She'd come back after five days and she'd stink and I'd be so jealous of how muddy she was!

"One year when they started the phoneline thing to call up for tickets... she was calling on the landline and I was calling on my mum's mobile and she got tickets and I didn't."

Jackson added: "You know sibling rivalry - I was so annoyed and I just said, 'I'm not going, I'm not going 'til I'm playing there'. Jessica was like, 'You're never going to play there' and I was like, 'I am, I am going to play there, and I'm not going 'til I play there'.

"Mum was like, 'Good on you!', because she didn't want me to go anyway... I went last year and it was pretty much like how I expected!"
