BBC staging unannounced flashmob operas

Flashmobs meet opera meet public transit: the BBC is staging unannounced flashmob operas at train stations.

[T]he BBC has announced that next month it will surprise commuters by staging an opera at an unnamed London rail station, without any warning.

The 65-strong orchestra and three opera singers will swoop in unannounced, with selected members of the public joining in as a chorus after being contacted at the last minute by mobile phone text message.
