Revelation Avenue Singers wowed with Roar by Katy Perry on Britain’s Got Talent 2015 Auditions.
The 12 piece gospel choir from East London impressed the judges with their rendition of the hit track.
Before taking to the stage they said: “We have been together since school, we broke up for three years and then decided to come back and take to the stage. This is the biggest thing we have done. We rehearse in a house.”
