Ed Sheeran treated his fans to a mini cover of 'Everybody' during a scintillating performance at the iTunes Festival last night (29.09.14).

The singer/songwriter slipped a few lines of the Backstreet Boys hit into his song 'Runaway' as he blew the crowd at the Roundhouse in Camden, north London, away with a barnstorming array of big tunes including 'Drunk' and 'Give Me Love'.

The flame-haired singer got his set off to the perfect start with a rendition of 'I'm A Mess' - one of the last songs he wrote for his second studio album, 'x' - and he was anything but the song title as he followed that up with a pulsating performance of his 2011 hit single 'Lego House'.

He continued his fine smorgasbord of songs with 'Don't' - widely rumoured to have been written about a previous relationship with Ellie Goulding - and couldn't resist injecting a bit of 'Loyal' by Chris Brown and 'No Diggity' by Blackstreet into the tune.

The star whipped the crowd into a frenzy with his energy and passionate voice throughout, but he asked for silence and encouraged fans to relax for five minutes as he sang the emotive lyrics to his tune 'Afire Love'.

As he prepared to sing the song, which was written about his late grandfather who suffered from Alzheimer's disease and died just weeks before he wrote the tune, he pleaded with the Camden crowd: ''This is the most meaningful song on the album. I'll ask you not to sing. Please just chill and relax.''

The calm continued shortly afterwards as Ed invited 'Afire Light' co-writer Foy Vance, who was also his support act last night, onto the stage.

The pair then set about wowing the crowd with a joint version of Foy's hit 'Guiding Light' before getting the audience back onto their feet with a triple threat of songs to conclude the main part of his set.

'I'm A Celebrity... Get Me Out Of Here! Now! presenter Laura Whitmore was among the supporters loving his work and she was seen getting into her groove as Ed launched into 'Thinking Out Loud'.

The star followed that up with 'Give Me Love' and asked the crowd, who he dubbed the ''gospel choir of Camden'', for some assistance, before completing his set with his 'I See Fire', which he wrote for the 'The Hobbit: The Desolation of Smaug' soundtrack.

For his encore, Ed rounded his gig off with a hat-trick of hits both old and new in the shape of a lengthy version of 'You Need Me, I Don't Need You', 'The A Team' and 'Sing'.

Plácido Domingo will conclude the iTunes Festival tonight (30.09.14).
