The singer appeared to scuffle with someone in the front row after she jumped down into the photographers’ pit to sing the final song of her set, ‘Rehab’.
In video footage of Amy Winehouse’s performance she appears to elbow someone in the front row.
The disruption saw security guards stepping in and leading Winehouse away from the stage before she could play her last song.
Police later said they had received no complaints following the incident.
It was a bizarre ending to a set that Winehouse began in high spirits.
“You don’t even know how happy I am to be here tonight. I feel like they should make up a new word in the dictionary for happy, and have a picture of me there,” she told the crowd before ‘Tears Dry On Their Own’.
She later joked about the small blue dress she was wearing, saying: “It took three women to get me into this dress. What is about women? It takes us ’nuff time to get dressed, but pow, no time at all to get undressed.”
The singer’s spirits seemed to darken, however, when she talked about her jailed husband Blake Fielder-Civil before ‘Back To Black’, the title track of her huge-selling 2006 album.
“My husband is out of jail in two weeks,” she explained, leading to a negative reaction from some parts of the crowd.
“Who booed?” she asked. “I’ll find you, take your phone, ring your mum and tell her about your bad manners.
“I thought I’d die with the man, then I was torn apart from him,” she continued. “I’m serious, I’d never loved a white man before – then he came and hit me over the head with a cricket bat. Not literally, obviously.”
Towards the end of the set, the singer’s comments between songs became increasingly bizarre. Firstly she asked: “Are there any black people in the crowd? Where’s Don Letts?” before ‘Love Is A Losing Game’, then launched into a tirade about Jay-Z and Kanye West.
She said: “Let’s hear it for Jay-Z. The man has got bollocks to come here, and play the tunes you don’t even know you remember. Imagine if it was a cunt like Kanye West. ‘Cunts Like Kanye’ – that should be his next album title.”
Winehouse then referenced her skeletal frame before a cover of the Dandy Livingstone reggae tune made famous by The Specials, ‘A Message To You Rudy’, asking the crowd: “If one of my ribs pop out, could someone catch it? I’ll reward you highly.”
She followed that with another cover of a Specials song, ‘You’re Wondering Now’, before ending with three of her biggest songs, ‘You Know I’m No Good’, ‘Me And Mr Jones’ and an aborted ‘Rehab’.
