This is Amici on stage in the BBC Regent Street Concert:

Regent Street in Central London was closed to traffic for the day from Oxford Circus to Picadilly Circus for a charity Event. Amici performed several live numbers and then did an interview afterwards for the BBC.
This a picture of Regent Street

In a small side street just off of Regent Street is the world Famous London Palladium, which is very deceptive from the outside, as it has in excess of 2000 seats.

The Regent Street Festival is held annually, and also gets a splendid Light Show at Christmas.
