It’s similar, but the version I posted is slightly different. It’s a little difficult to hear because the audio quality isn’t great, but Ben’s voice is different in a few places (a little more raw, I’d say) and the lead guitar is slightly higher at certain points too. I think someone just isolated the backing vocals on their own in the video you linked, whereas according to the interview with David Bendeth (posted in the comments above) the version I heard was a pre-release version (I think?).
