Just discovered this on Youtube and came here to see if any of you guys posted. I'm pretty sure this is just an edited HSCpt2. Anyone remember that Beastie mashup, that one DJ did that had the original Make Some Noise? The OG Make Some Noise didn't have the "Party on the left/right, Right to Fight" prechorus part, which I'm sure was recorded later, especially considering it fits with FFYR Revisited.
Really wish this was legit, but even B-boys in the Cut sounds exactly like the fan mashup of the pella with the "El Bando" instrumental from 2009, which is why the vocals are off beat.
