Arcade Fire say headlining Glastonbury was one of ''the most incredible'' moments of their career.

The indie rockers - who performed on the Pyramid Stage at the iconic Worthy Farm festival on Friday night(27.06.14) - kicked off the set with their 2013 single 'Reflektor', which was accompanied by a firework display, and labelled the experience ''unbelievable''.

Lead singer Win Butler told the crowd: ''We're so happy to be here at Glastonbury.''

During the opening track, the 34-year-old took a camera from a lucky reveller and snapped a number of photographs before handing it back, while the crowd let off red and blue flares, prompting Win to say,' Thank you for the flares, I hope you don't get arrested''.

The Grammy Award-winning band - made up of Win, his wife Régine Chassagne, his brother Will Butler, Richard Reed Parry, Tim Kingsbury and Jeremy Gara - were scheduled to be joined on stage by Australian singer Lorde, until the 17-year-old pulled out of the show to spend time with her family.

Lorde - who wasn't booked to play in a solo slot across the weekend - tweeted her disappointed at missing the performance.

She wrote: ''Pulling out of Glastonbury in the name of family time was a tough decision but oh boy I am not jealous of that mud.''

Meanwhile, performances on the Pyramid Stage were brought to halt yesterday evening after thunderstorms forced organisers to cut short Rudimental's set.

Instead of broadcasting footage of the performance, the screens at the side of stage showed a warning message before a festival representative came out to inform the crowd the stage was being closed.

The closure led to a delay in the festival's performance schedule causing Lilly Allen's set to be cut down.
