Moonlight Densetsu
Translates to "Moonlight Legend". This was the first ever Sailor Moon theme song, and it is in Japanese. Two different versions were used for the anime, but it was replaced in the fifth season with Sailor Star Song. The basic melody was used for the theme song in the English version, as well as several other non-Japanese dubs.''Sayonara wa Dance no Ato ni'' provided the melody originally.
