Props to you for doing it. I've invested a few thousands into equipment for my son and it hasn't gotten out of the basement.

The singing in this vid was on key and everyone kept in beat.

This is more of a 'Guns and Roses' version and the lead guitar is no way near Rooster's capability (especially during the solo bit - the notes sounded flat for most of it). IMO, the mic distortion really hurts. Michael Schwarz is right. The instruments aren't balanced with each other. The keyboard over powered the rest of the instruments and I barely heard the drums or the bass at all.

I'm not saying anything here to discourage you guys, rather to provide opportunities for improvements.
