I saw this Paramount flick quite a few times, back when I was a projectionist just out of high school at the local art movie house, (this was circa 1982). I remember it being a mixture of dry documentary stuff and wonderful musical bits. Of the docu part I remember a scene where they hook a plant up to electrodes and measure it's sensitivity while they chop a head of lettuce in front of it (the plant freaks out on the machine's readout). I also remember a cool time lapse sequence with flowers blooming while they play "Here Come's The Sun". And the bits with Stevie Wonder wondering through a field of flowers was cool (and comical, as there was nothing for him to bump into). I've searched for years for this on video but I'm sure it's held up in musical right's limbo (that and the fact that no one's ever heard of it).
