Bonjour Mr Aznavour

In the final programme of the series, Petula Clark looks at Charles' success in America, and traces his roots back to Armenia. She also considers Charles' standing today and what will happen to the tradition of chanson when he retires from performing. Contributions come from Nana Mouskouri, Josh Groban, Canadian/Armenian film director Atom Egoyan, lyricist Herbert Kretzmer and Paul Gambaccini.
