I'm REALLY sorry if this is in the wrong section. There was one kind of similar to this told to go to the marketplace section, but I'm not sure if this would qualify to be there, either.

On BeForU United, in the only review available for Graduation ~Sorezore no Ashita~, I was alerted that the version of the song I have is most likely not the original.
Would anyone happen to know which CD the original is on, and where I could buy said CD?

It's probably the short unplugged version from BeForU First Album or BeForU. I believe it is out of print. You can probably get itrade or buy it from the marketplace.

Except he/she's asking where to find the original version, not the unplugged version.

The original Graduation is as far as I know only on the DDR Extreme soundtrack. (track list here). The short version is track #1, and the long version is the bonus track on the first CD. You can buy it here from CDJapan or here from play-asia.

For future reference, something like this might go better in this thread or someplace similar. This board is pretty much for forum feedback. At least you tried, though, so I won't fault you for that. XD

Or you can probably download for bemanistyle or the short version from DDR LOVER.

Oh!.. If it's the one on that CD, then I already have it! ^^ I got that CD a couple years ago when I got started on DDR! Thank you very much! Though I don't recall there being much of a difference in the one I have here and the one I have on the CD, I'm glad to know that I have the original.

I'll post all other questions in that thread. ^^ Thank you guys so much, again!
