I'm just watching through it now, and I noticed it's using the studio version of FAS over the intro video.
The mix is nice overall. Usually they bury the keys in the mix with these festival broadcasts, but I can hear it nice and clear. They usually bury the background vox too, which is the case earlier in the show, but I can hear JP better as the show goes on luckily.
The drums sound a little wimpy, but ok. JLB sounds like he's having trouble with the higher range on the earlier songs, but seems to improve over the show.
