Sonic CD (JP Version) Intro, Bad Ending, Good Ending Credits

This is how the Japanese Soundtrack for the new Sonic CD port should of sounded like, Unsure why there are no lyrics, I think it was something to do with the singer passing away...
R.I.P Casey Rankin!
(Christian Whitehead aka "The Taxman" followed the discovery up with the below message at the Sonic Retro forums suspecting legal rights issues.
I know it's a bit of a bummer that the vocals had to be left out. It's definitely not something due to laziness or something silly. I couldn't tell you the circumstances, but at least from my understanding there are some rights associated with the lyrics themselves.
My guess is that since Casey Rankin is no longer alive, there might be problems negotiating the use of the lyrics outside of Japan. Please, don't take this as gospel though since I don't work in legal)
