Ghost also played Stand By Him.
So it seems like they are only cutting out Genesis and Here Comes The Sun from the headliner set they were playing. Not much by any means but it hurts a little since those are amazing songs. I'll never get over missing their headlining run
On another note, I am disappointed in the Mastodon setlist. I think there is a handful of weak songs on The Hunter and unfortunately for me they are playing them all. Would it have killed them to throw in some Remission songs?
