The Glastonbury Festival 2010 took place between 23 and 28 June. On the last night, Michael Eavis appeared on the main stage with headline artist Stevie Wonder to sing the chorus of the latter's "Happy Birthday", marking the festival's 40th year. Tickets went on sale on 4 October 2009, using the same £50 deposit scheme introduced the previous year; unlike the previous two years, and more in common with earlier festivals, the tickets for the 2010 edition sold out in less than 24 hours. U2 were due to headline the Pyramid Stage on Friday night at Glastonbury 2010, but due to frontman Bono sustaining a back injury they were forced to pull out. According to the media, Bono was "gutted", even having written a song especially for the festival. Damon Albarn's Gorillaz replaced U2, and joined Muse and Stevie Wonder for the Saturday and Sunday headline slots respectively. It was Albarn's second headlining act in two years. Pet Shop Boys returned after 10 years to headline the Other Stage on the Saturday Night. The entire stage set from their Pandemonium Tour was brought in for the performance which was extremely well received. Radiohead's Thom Yorke and Jonny Greenwood made a surprise appearance with a nine-song set. The weather at the festival was among some of the best ever, the festival-goers enjoying 3 days of abundant sunshine and very warm to hot temperatures, which reached close to 30 degrees on the Sunday; it was the first rain-free festival since 2002 and the hottest since the festival began.
