Who: Mumford & Sons
Where and when: NME/Radio 1 stage, Leeds, 7.55pm.
Vibe: Euphoric, beautiful and utterly packed. Despite going up against Queens Of The Stone Age, Mumfords scored a victory for folk.
Hundreds of people stood outside because they couldn't get into the tent and a sea of faces screaming the 'Little Lion Man' lyrics at the band was definitely a moment of the festival.
With all their success over the last year, it's easy to forget what makes them great. With hundreds of people singing-along, suddenly their lyrics meant a whole lot more again.
Best bit: Watching Marcus Mumford play drums on new track 'Nothing Is Written'.
Low point: They were on the same time as Queens Of The Stone Age. Ideally it would have been nice to fit both in - but that's the way of festival scheduling.
Banter: Marcus Mumford to the crowd: "You're much more attractive than Reading." Cue even more euphoric screams.
Verdict: The Mumfords got a very, very well deserved reception from the nicest crowd of the festival season.
