Which song plays while Hughes and Mustang talk during episode 30 of FMA:B? In episode 30 of Fullmetal Alchemist: Brotherhood, the song starts playing 12 minutes in while Hughes and Mustang were talking. It sounds like Requiem for the Brigadier General, except it's a soft piano.

Is it a different version of the same song? If so, I can't seem to find it.
It's Happiness ~Requiem from The Blind Alchemist~ by Akira Senju, the 28th track from the album Fullmetal Alchemist Brotherhood Original Soundtrack 1.
