Sorry man, I just hit all of my usual sites and I got nothin'. I see Abdel Wright released a CD in 2005, the same year that "Into The Blue" hit theatres, but "Remember" wasn't on that CD. I'd imagine "Into The Blue" had a soundtrack, but it must not have sold very well because it has totally vanished.
Have you tried any of the pirating options, such as LimeWire? SOMEBODY out there must have it. That may well be your only option.
You could also try e-mailing the company that produced the movie. I did that a few years ago because I wanted to find out where to get a piece of background music from the party scene early in the movie "Rules Of Engagement," and I was amazed to get a very quick reply. But it turned out the song in question was written by the composer specifically for that scene, so it was only a minute long and wasn't available for sale. Drat... loved that guitar riff too. Ah well. Anyway, since you'd be asking about an actual honest-to-goodness song written by an actual honest-to-goodness commercial musician, you might have more luck.
