I might just be slow to this as I don't usually watch live videos, but Chester's voice now is very very different than how it used to be in HT days. Upon watching the newly released (and uploaded) DVD, I found the old songs to sound a lot different due to this change. I'm not keen on how to describe it, but the raspiness, xcoreness is all gone now, it's replaced with a deeper smoother voice. This makes the old songs sound like Chester's singing on a different key. Again, I might just be slow in noticing this but it was a drastic change as I heard it.
