I'm neck deep in Anime and other Japanese stuff. However finding CD soundtracks (especially older ones) can be difficult at times and utterly and literally EXPENSIVE!!! However in the past year I've found several out of print items from Japan that have literally been unatainable elsewhere. Props to you Amazon! The prices are usually about what I pay for them once shipped from Japan but still...no complaints. One word of caution, the one's that are fulfilled by Amazon seem to be orginal manufacturer's productions. However, be weary of copies from other sellers. Some are bootlegs.
For anyone that has seen this series, it should be well know that it's a musical. These are just a few tracks that are found in the original Japanese production.
