The sound isn't that great on the video. Much clearer on your Myspace and even clearer on the download so I'll guess you used a lower quality file for the video. And if you used windows movie maker that seems to numb parts of a music track too. Since Youtube began to focus on HD I've noticed a general drop in quality of all the non HD videos. Maybe you should try it on LiveVideo.com which seems to have better clarity, although it has less traffic.
I like the arrangement. Being a Northerner I quite enjoy brass (or silver) bands although they don't seem to transfer well to video channels. The kinda distant effect of the vocals only works if you adjust to the idea. Quite a few less commercial concept/progressive albums of the early 70's worked with similar ideas, so it might be a bit retro for some. I applaud the fact that it doesn't just follow the norm, but you have to be prepared to be criticised for it too. A lot of people don't want or accept this kind of off-beat thinking. I doubt you'd get past the BGT panel.
Love the old black and white footage in the video which fits well with the music.
