During her years in college, she sang on a radio station in Los Angeles, California, and changed her name to Eileen Wilson, taking her voice coach's last name.
In 1950, while singing on the Hit Parade radio program, Wilson became one of the original starring vocalists—with Snooky Lanson and Dorothy Collins—on the TV version of the show.
Wilson dubbed many actors, including Ava Gardner in One Touch of Venus and The Hucksters,[5] Jayne Mansfield in The Girl Can't Help It, Sheree North in The Best Things in Life Are Free (film), and Barbara Bel Geddes in The Five Pennies, among others.
For those recordings, she sang note-for-note recreations of songs such as "A Sunday Kind of Love" (which had been a hit for vocalist Fran Warren with the Claude Thornhill Orchestra) in the style of the original singer.
In 1972, she performed (along with Hit Parade stars Gisele MacKenzie, Snooky Lanson, and Russell Arms) on an ABC-TV special, Zenith Presents: A Salute to Television's 25th Anniversary.
