Changes to music video

I have only just finished my first draft of my muisc video, but already there are obvious problems which I need to change, there are certain parts where the singing of my front man does not sync up with the track at all.so this will need to be adressed, and the unavoidable guitar solo midway through the song. I have previously stated that my band are not actually a band, so this is difficult and I am currently working on a solution to this problem.
