(written from a Production point of view)
Loulie Jean Norman (12 March 1913 – 2 August 2005; age 92) was the soprano who sang the wordless accompaniment to the theme music of Star Trek: The Original Series. Her voice can also be heard in the eerie music that accompanied the Talosians' illusions in "The Cage", also composed by Alexander Courage. This segment was recycled in the seance in "Wolf in the Fold", Nona's treatment of Kirk from a mugato bite in "A Private Little War", and the scene where Spock is first possessed by the spores in "This Side of Paradise".
Norman's singing voice can be heard on several films. She was a background singer on the 1954 film Brigadoon and the 1955 film The Prodigal. She was also the singing voice for Diahann Carroll's Clara in the 1959 Porgy and Bess, which starred Brock Peters.
