Green Day play one-hour set at Reading Festival
The California trio surprised fans by taking to the NME/Radio 1 Stage an hour ahead of their rumoured slot.
Shortly before the band emerged, frontman Billie Joe Armstrong tweeted: "Green day - READING FESTIVAL CONFIRMED!! On stage in 45 minutes! In the NME / RADIO 1 tent. 11am!! Be there!"
The band then went on to play five tracks from their third album Dookie, before launching into more recent hits 'Letterbomb', 'Hitchin' A Ride' and 'St Jimmy'. It had been rumoured that the entire setlist was to be composed of tracks from the 1994 release.
Festival attendees were so eager to see the band that the organisers had to close off access to the tent, which meant most of the crowd was forced to watch the band on the Main Stage, where the performance was being shown on a big screen.
Organisers also attempted to get the band to finish at several points during the 60-minute set, but Armstrong was determined to carry on and shooed away members of the crew who tried to turn off his guitar.
"F**k time, I'm going to play for as long as I want to," he told the audience, before being forced to cut the band's 2004 single 'Boulevard of Broken Dreams' short.
"We're having a little f**king problem with time," he explained.
The band continued playing, even after video coverage on the Main Stage ended, and a large group of fans then gathered to watch the remainder of the 12-track set on a distant screen from behind a security cordon. Throughout the gig, Armstrong praised the Reading audience's passion and dedication.
"That's why I f**king love England," he said. "The Americans just don't get that s**t."
Notably absent was material from the band's new album trilogy, ¡Uno!, ¡Dos!, ¡Tré!, which is due to be released in three stages. The first album, ¡Uno!, will be available from September 24, with the second LP, ¡Dos!, coming out on November 12 and ¡Tré! following on January 14, 2013.
Green Day are also releasing a pair of documentaries alongside the album. One is said to focus on the making of ¡Uno!, ¡Dos!, ¡Tré!, and the second is being pieced together using vintage footage shot during the band's early, pre-Dookie' days.
