ER star Parminder Nagra has appeared in a live one-off Broadway stage performance, to encourage New Yorkers to visit London. The commercial, which took place before the show STOMP yesterday (23MAY05), is one of several taking place around the world. In the advertisement, a couple discuss London attractions and an actress, planted in the audience, sings the city's praises during a mobile phone conversation with her daughter. The ad has so far taken place in Hamburg, Germany; Dublin, Ireland; and Pittsburgh, US.
