It was a charity concert – Young Voices. Loads (like dozens) of school choirs, who’ve all been learning the same songs independantly and then go to the O2 (or other big venue if you aren’t a London / SE school) and get to sing them all together, with a proper backing band, conductor, proper soloists, African children’s choir, etc.
Lovely evening out, my eldest was singing with her school, among about 5000 others.

Their main website is down, seemingly due to traffic trying to find out if tomorrow’s MEN Arena concert will go ahead but here’s a related one.
