WATCH: Ed Sheeran joins James Bay on stage for ‘Let it Go’

Introducing what could quite possibly be the duet of the year so far - James Bay and Ed Sheeran.

We know, we know - cue fangirl mode.

Bay was performing an intimate gig in Cambridge over the weekend, when he casually surprised the crowd by calling Ed Sheeran to the stage - as you do.

The two first met at the The Brit Awards earlier this year where Bay won the Critics' Choice award and of course Sheeran took home the British Album and British Male Solo Artist awards.

Yes, you guessed it, the duo launched into Bay’s hit single ‘Let it Go’ and it is everything you imagined and more.
