Unless some dancers were filling in for taping or Dress, Foster, Eames, and Griffiths were cast in the "Emeralds" Pas de Trois, not the leads, and not always with each other in the PdT. We have the leads from 2006 and 2009 pretty well documented here. Foster also danced in "Rubies."
I thought that looked like Korbes in "Diamonds." Maybe Bold partnered her in Dress?
sandik: do you remember there being unusual casting in the Dress Rehearsal for "Jewels?"
