There was a thread in which I posted a few people I considered to be SEI, based on my own thoughts and the insights of others (many of these may be too British or too irrelevant...):

But I would now refine the list to:
Alison Goldfrapp
Anne Marie Duff
Mel Giedroyc
Emma Hamilton
Iggy Pop
Twiggy
Olivia Hallinan
Dawn French
Peter Lorre
Adrian Edmondson

Also:
Róisín Murphy - very possibly
Stephen Fry - yes, I can see that
