I remember first watching it on TX Network [and on Animax] long time ago, in 1996 or 1997, I believe. It's certainly is my most-beloved classic anime series ever.
The soundtrack kicks ass!! I especially love the song: 約束はいらない [Yakusoku wa iranai]. As an aside: Translation - [Yakusoku - promise, iranai - don't need].
Basically, anything of Kanno Yoko and Sakamoto Maaya rocks!
