The 'Broken Record' singer 30-minute set at the packed out venue in Camden is very happy when fans "something special" was promised.

She said: "Right Camden, I'm going to do something special for all of you tonight. A little treat for you. This is for all of you ravers out there.

"All of you guys and girls who were raving through the 90s. I've been rehearsing this for ages so I hope you like it."

Katy perform at the Combine, which included Robin S's 'You Got to Show Me Love' and En Vogue's 'Back To Life'.
