Hi Hardcore
I don't know the original song, but that sounded and looked good. You have a great voice (or is that your brother?) and between you, you sound good and current. If I were you I would be getting your own songs video'd like this to promote yourselves!
How did you do the video - what sort of video cameras, or was it done on phones, and how did you edit it/sync the cameras? I only ask as this is not an area I have much experience of.
cheers
Dave
