“We are here to celebrate women tonight and their survival,” said Pharrell Williams as he took to the stage during the ‘We Can Survive’ concert to benefit breast cancer charities. The ‘Happy’ singer was joined by a host of other stars including Taylor Swift, Gwen Stefani and Ariana Grande to raise money for the Living Beyond Breast Cancer and Young Survival Coalition.

As well as performing renditions of hits such as ‘Get Lucky’, ‘Different’ and new song ‘Come Get It Bae’, Williams also joined friend and fellow 'The Voice' judge Gwen Stefani on her classic track ‘Hollaback Girl’.

Also performing was Taylor Swift who mixed in old favourites such as ‘We Are Never Ever Getting Back Together’ and ‘Trouble’, with new tracks ‘Out Of The Woods’ and ‘Shake It Off’ from her forthcoming album 1989.

But among the stars and lively performances the true message of the evening was never lost on the audience. Coming back onstage to close the event, Pharrell was moved to tears by the crowd’s response.

The singer had previously spoken earlier in the evening of loosing his grandmother to breast cancer, and told the audience “So you all made me cry, let’s finish the show,” before ending the night with an uplifting performance of ‘Happy’ as fireworks were let off in the background.
