I would suspect that not everybody knows that Olivia'a most successful career began in an "artificial" way
as it says on:-
http://www.onlyolivia.com/visual/toomorrow/about.html
"In 1970 Olivia made her second movie entitled Toomorrow. Don Kirshner, who had created the Monkees in 1965, wanted to repeat this success and manufacture another pop group. He teamed up with Harry Saltzman maker of the popular James Bond movies. The group Toomorrow was to be launched via the cinema and via an album and single"

(For some obscure reasion for me the above picture was exceedingly slow to download, it is not actually a very large file either(only 75994 bytes for a jpeg of only 74 by 432 pixels so dial-uppers be patient!)
"The film opened amidst much publicity Bruce Welch, who was Olivia's boyfriend at the time, had this to say about the film and music: "The film was a disgrace. It was reminiscent of so many of the low-budget pop pictures that were made during the early sixties, and the biggest let down of all was the music. It was all so lightweight""
Bruce was himself of course a member of (Sir) Cliff Richards's group The Shadows and Olivia went on to be one of the few girlfriends attributed to the never married Cliffie-boy.
She had a way of making sweet sounding covers of major folk hits.I especially like her cover of John Denver's "Take Me Home Country Roads"
