Edie Sedgwick (and a silent Andy Warhol) on Merv Griffin show in 1965 is a mindboggling time capsule of who we were 50 years ago. Her accent no longer really exists, making her sound like a foreigner even though she's a descendant of a signer of the Declaration. The self-awareness of the "ridiculous" nature of what they're doing is telling.
Very rare to hear her talk at any length, her parts in Ciao Manhattan were mostly dubbed by an actress since she died during production.
