Who is The Cello Player (The Living Daylights) from Octopussy and what is their importance?

The cello player is one of the members of an all woman's orchestra which goes in and out of the Ministry of Culture while Bond is waiting to cover the escaping agent's crossing of the no man's land between East and West Berlin. A tall girl, she has long straight blond hair and her pale profile shows gaiety and happiness as she chats with her fellow musicians.
