A few weeks before the 2015 festival Foo Fighters frontman Dave Grohl fell off a stage during a show in Gothenburg and broke his leg, forcing their late withdrawal from the line-up. Florence and the Machine were moved from second-top on the bill to Friday's headliner, while Florence's vacant gap was filled by Reading & Leeds headliners The Libertines, and their performance was well received. Kanye West and The Who were the headliners for the Saturday and Sunday, respectively. Other notable acts who performed included Motörhead (their final festival appearance in the UK before Lemmy's death), the Moody Blues, Pharrell Williams, Deadmau5, Patti Smith, the Strypes, Lionel Richie, Catfish and the Bottlemen, Enter Shikari, the Chemical Brothers, Thee Faction, Alt-J, Paloma Faith, Mary J. Blige and Paul Weller, as well as an appearance by the 14th Dalai Lama. On 28 August 2015 it was announced that hundreds of pairs of discarded wellington boots from the 2015 festival were donated to the migrant camp at Calais.
