Music & fashion, 6th of 6 -- Stardust memories

Nostalgia might be the very opposite of fashion, but it creates new fashions. Nostalgia for a time when the world still had style leads to cocktail drinking and Diana Krall. Did such times ever really exist? Why have certain types of music been fashionable at certain moments in history, and what might this tell us about the way in which human beings hear, appreciate and use music? Presenter Andrew Ford explores the transitory (and often unmusical) nature of fame.
