Here is the link to the first section of an ace documentary from BBC four (from a couple of years back) which I have recently enjoyed.
The blurb from the BBC is:
"The story of 1920s London's Bright Young People is a tale of sex, drink, drugs and a gossip-hungry press. Beautiful and Damned traces the growth of 1920s London's bright young party set whose antics were enjoyed and scorned in equal measures by a watching nation. And the more artistic of the merry band - Cecil Beaton, Evelyn Waugh and Nancy Mitford among them - saw their work make the characters and attitudes of the era both legend and fable."
What an incredible period of time to be rich and young - a bright young person. Their treasure hunts around London sound insane!
