I have to say after hearing the 1987 cover all these years, it was a shock to hear the original version of "From The Planet With Love" by PSY-S. It was never made into an official single but was a track on the duo's first album, "Different View", released in May 1985. Frankly, it sounds like a raw demo track and a rather flat and tinny one at that.
Then, a couple of years later, Masaya Matsuura（松浦雅也） and CHAKA re-tooled it into the much more boisterous piece that I love as one of my favourite PSY-S tunes. The tempo is a bit faster with more robust synths and CHAKA can get a bit more down with the lyrics, including that rap she does in the middle. The '87 version was the one I first heard via one of their BEST albums, "Two Hearts"(1992). I had first thought that the song was created for some sort of World Peace project considering the title and lyrics (all in English), but apparently not. Still, a cool song.
