Plus Lightspeed Champion and Speech Debelle round off day two of the London festival
The band played singles 'Nice Guys' and 'Rules Don't Stop' from their forthcoming album 'Barbara' and old favourites 'The Great Escape' and 'Nobody Move, Nobody Get Hurt' to the packed venue.
They were also joined onstage by Dev Hynes from Lightspeed Champion for 'Pittsburgh', 'Jack & Ginger', 2008 hit single 'After Hours' and 'Ambition'. The singer made the surprise appearance after Keith Murray joined him onstage during his set earlier in the day.
We Are Scientists played:
'This Scene Is Dead'
'Let's See It'
'I Don't Bite'
'Nobody Move, Nobody Get Hurt'
'The Great Escape'
'Rules Don't Stop'
'It's A Hit'
'Jack & Ginger'
It was a busy festival for We Are Scientists, who also played a secret gig at Lock 17 to just 20 fans, performing a stripped-down set in the bar to kick off the evening.
Earlier Lostprophets also played at The Roundhouse, arriving onstage to the sound of air raid sirens and hundreds of screaming fans as the Welsh rockers played fan favourites 'Last Summer' and 'Burn Burn' before starting an audience singalong to 'Holding On' and 'Last Train Home'.
Elsewhere, the members of Gaggle squeezed onto the stage at the Electric Ballroom - playing the first gig with a percussionist - having previously won Best New Band at the Emerging Talent Camden Crawl Awards. Adorned with fluorescent tribal face paint and giant headpieces, they performed a set which included ‘How Can I Tell If My Man's A Liar?’, a cover of Marina And The Diamonds' 'Mowgli's Road' and debut single 'I Hear Flies'.
Lightspeed Champion then followed them at the same venue, occasionally joined onstage by We Are Scientists' Keith Murray as he performed material mostly from new album 'Life Is Sweet! Nice To Meet You'.
Delays, meanwhile, played a mixture of new songs and old favourites to an overflowing Cuban Bar. While they performed former single 'Nearer Than Heaven' a fan was ejected, prompting his friends to chant, "Tell them to let John back in!" between songs. The band were happy to oblige and led a chorus of "bring back John" before playing a string of tracks from upcoming album 'Star Tiger, Star Ariel'.
There was a queue stretching down the road when Chew Lips played at The Black Cap, with singer Tigs telling NME.COM that Camden Crawl was important to the band because their performance at last year's festival "was a turning point".
The frontwoman explained: "It was the first time the entire crowd sang the songs back to me, I didn't need to sing! I came off stage and I really, really cried, I was really emotional, it blew me away."
At The Electric Ballroom, 2009 Mercury Prize winner Speech Debelle played the likes of 'Buddy Love' and 'Bad Boy' as well as new track 'Going Places'.
As the rapper kicked off the track, she told the crowd: "It's not finished yet, we're still working on it but we want to play it for you."
Kyte kicked off their 7.45pm set upstairs at The Black Heart with 'IHNFSA'. "We’re called Kyte and we're from Leicestershire," announced frontman Nick Moon, before asking the crowd packed into the small room, "Is everyone having a good Camden Crawl?"
Elsewhere, Surfer Blood's frontman, John Paul Pitts, finished the band's 9pm show at The Underworld by crowd surfing into the middle of the venue, ending the an energetic set which included 'Swim' and 'Twin Peaks'.
Over at the Blues Kitchen, Veronica Falls took to the stage at 10.40pm, arriving 25 minutes after their scheduled time of 10.15pm.
Occasionally distracted by an over-enthusiastic dancer in the front row, the band played an impressive set of 80's-influenced pop despite experiencing sound problems.
In the Camden Rock, Comanechi played a typically riotous set as singer Akiko, who was dressed in shredded tights and a floral leotard, led the band through songs from recent album 'Crime Of Love'.
Later in the venue, Yuck closed the Camden Crawl despite arriving onstage 20 minutes late.
The band played single 'Georgia', as well as new songs 'The Wall' and 'Suicide Policeman'.
