Was watching the social link scenes from FES; The Journey, and I noticed the remixed version of Memories of the School, but it was nowhere to be found on the actual OSTs I downloaded from various searches. So after some digging around, I found a guy on youtube named Lunardragon2607 had ripped it and posted it there, so I thought I would pass the link along to you all. The other confusing thing is that from what I gathered the song is actually called Memories of the Garden. He also has extended versions of a lot of the songs from Persona 3 and 4. All the credit goes to him though, I'm just the messenger.

There is also a direct mediafire link in the video description, but some of his MF links are not online anymore.

Quite an eye opener, thanks!
