Our Life....the problem

With the song we ran into a problem as the 2 artists on the record are unavaliable to record the song, but where i was one of the people that produced it i have rights to use the song for this and have decided that we will use this song to make our music video to. So because we are unable to get the artists we are going to be having different people mime the lyrics so it looks like everyone in the actual video is rapping along to the song. We took the insperation from a song by So Solid Crew called Broken Silence
