This insipid science fiction musical concerns a group of students paying their way through school by forming a pop band. The group is led by Olivia Newton-John, and organist Vic Cooper has invented an instrument called the "tonaliser." The sonic vibrations from the invention causes an extra-terrestrial (Roy Dotrice) to beam up the group to entertain the Alphoid population. The film title refers to the group name. Newton-John would go on to a successful singing and acting career, most notably in the 1978 musical Grease.
