From the Dead Rock Stars Club -
Loulie Jean Norman - Died 8-2-2005 in Los Angeles, CA, U.S. - She was 92 years old - Singer - She sang the wordless vocals for the theme to the original “Star Trek” TV show - Worked with Frank Sinatra, Sam Cooke, Elvis Presley, Dean Martin, The Ray Conniff Singers, The 'Gordon Jenkins Singers and Spike Jones & His City Slickers.
She probably didn’t want to be known soley for that theme, but I’ll bet there are very few Americans who haven’t heard that haunting voice.
