Florence & the Machine and the Final Fantasy video game franchise aren't what you might call natural bedfellows, but the singer has provided a cover of a classic soul song for the soundtrack to the latest installment.

Her take on Ben E. King's 'Stand By Me' can be heard at 1.10 in the trailer below.

She said: "I’ve always seen Final Fantasy as mythical, beautiful and epic. 'Stand By Me' is one of the greatest songs probably of all time and you can't really improve on it, you just have to make it your own. For me it was just about bringing the song into the world of Florence And The Machine and the world of Final Fantasy."
