All Hail Shadow Fearless Remix v1 - (Magna-Fi's Beta 4 + Crush 40 with Orchestra Opening) 

It isn't perfect and took way too many tries to get this done, but it's here.
I used an extended orchestrated version from the ending of "Mephiles Whisper"for the intro. The mashup/duet itself is uses Magna-fi's Demo and Crush 40's cover.
When I get around to v2 it'll invert who sings which part of the 1st verse (v1 has Magna-fi followed by Crush 40)
