Coldplay performed Lou Reed's Perfect Day during Sunday's headline set after the Velvet Underground legend asked Chris Martin to do him the 'favour' during a backstage chat.
During his own set, there had been murmurs of disbelief within the crowd as Lou Reed departed the stage without having played his best known song. But disappointment turned to delight when the Coldplay frontman revealed that Reed had cornered him backstage and asked him if he'd perform the song instead, to placate the crowd.
"When Lou Reed asks you for a favour, you do it!", said Martin on-stage during his band's headline set at the end of the night.
Coldplay's version thrilled the crowd but was anything but perfect with Martin laughing and swearing repeatedly as he fluffed up his lines. He made up for it by attempting to recreate M People's Heather Small's famous warble on the more recently released all-star version of the song and later he revealed that the band had only had 20 minutes to rehearse it.
Throughout their set, Coldplay were on inspirational form with Martin rolling, diving and crabbing his way around the stage. He was happy to share the limelight, though, inviting guitarist Jonny Buckland to sing on 'God Put a Smile on Your Face' and inventing his own UK Festival Award, dubbed 'Festival Fan of the Day' to a young girl who was invited up on stage and presented with a bottle of Champagne to glug whilst she watched the band perform at point blank range.
Highlights from the set included 'Talk', 'In My Place', 'Politik' and 'Yellow' with the band finishing on their now customary closer 'Fix You'. The set capped an already perfect day at the festival with the crowd lapping up afternoon sets by Delays and Kubb.
But the most anticipated star was Lou Reed who played as unpredictable a set as you's expect, frequently deviating into experimental jams, sandwiched between classics such as 'Waiting for my Man' and 'White Light/ White Heat'.
Richard Ashcroft followed with an impassioned set packed with songs from his latest album including 'Keys to the World' and 'Music is Power'. But the highlights inevitably came with Verve songs 'Lucky Man' and a solo acoustic 'Drugs Don't Work', with Ashcroft baring his soul concerning his depression, at one point telling the crowd how he almost killed himself last week. The crowd responded supportively to his honesty and were rewarded with perhaps the moment of the weekend – an epic extended 'Bitter Sweet Symphony'.
The only rival to that crown would be Procal Harem's 'Whiter Shade of Pale', performed earlier in the day, the Isle of Wight veterans returning to the festival after last playing it in 1970. All in all, a spectacular and memorable festival weekend.
