Did this as a DIY mix a couple years ago... I really love how it came out. I had to use a combination of two different stem bundles, Rockband and Jammit. I also had to create the repeating background vocals ("Just do your best... do your best" etc). There was also an alternate lead guitar solo (of course it doesn't come close to the classic solo) which I placed at a low level in the left rear. I've done a lot of crappy surround mixes, but this is one I still like to hear
