Fantastic! She was the only one with such charisma. I think Merlin Monroe had something in her or perhaps she studied Dietrich's interpretation and moves.
To say that she sung with her soul , is true , but it's more true to say SHE SUNG WITH EVERY ASPECT OF HER BEING ! her pinky toes , her eyelashes , SHE GAVE EVERYTHING THAT SHE HAD TO GIVE - SHE WAS MARVELOUS !
