And not to put down the melody...it may be milder in comparison but in its quieter but no less epic way, Hirao and lyricist Jun Hashimoto（橋本淳）have been able to convey the incredible adventures that the Three-Nine has experienced. I also enjoy how the song just fades in after the train starts chugging down the tracks. Furthermore, I'm not sure whether Hirao had been aiming for this combination, but I could pick up hints of Mood Kayo and City Pop through the arrangement such as the percolating bass. "Ginga Tetsudo 999" is the musical passport for your voyage through the stars.
"Aoi Chikyuu" was actually the first song that I had heard which was connected with "Ginga Tetsudo 999" via the instrumental version in the trailer for the first movie in 1979. The single, and I'm assuming that the two songs occupied the same 45", became the No. 1 song on Oricon in the Anime/Children's Songs category for that same year.
I borrowed the videotape of the original first movie only having seen certain pictures of the mysterious Maetel and the train along with catching some scenes here and there from the TV show. So I didn't know too much about what "Ginga Tetsudo 999" was all about and since my copy of the movie had no subtitles, I couldn't understand everything about the plot. However in compensation, the animation and soundtrack were just gorgeous so by the end of the movie, I really wanted to live in the far future. The above video shows the movie, and at the 2-minute mark, the orchestra ramps it all up with what I think is a short but magnificent tribute to "Aoi Chikyuu". Fans couldn't have asked for a finer musical introduction.
