I've been obsessed with this film for ages...it's like a bizarre Partridge Family on acid with a happy sorta Wild In The Streets meets Star Trek vibe if that makes any sense. It's called Toomorrow & was released in 1970. Here's some info from an olivia newton-John fan site:
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.
The group consisted of Australian 21 year old Olivia; English keyboard player Vic Cooper 25, American drummer Karl Chambers 22 and Ben Thomas American 24 year old singer. Originally Chirs Slade (who went onto ACDC fame) was to be a member - but before the movie was made he left and was replaced by Karl Chambers (Karl sadly died Feb 2002 from cancer).
There is a record as well, great odd music! Someone put the whole film in 11 parts on Youtube! here's one clip:
Don't freak out!
ps. 4/2008: oh no! it's gone ... but don't fear, the slammer team bought the film!
