Not to worry, they've got a clever trick up their sleeve they've been very deliberately holding out on until now, when it would have the most impact: downtu-hahahaha yeah right. Rime should be easy enough, it's RTTH as the last encore I'm worried about. 2018 he was still incredibly on form, but now it's seven years later and Bruce's voice isn't really there in the same way.
He can push it in the first few songs, but by the encore it's really obvious he's way out of his natural range by now. That's how the cookie crumbles, no matter how much he or his fans want to deny it. You can't fight nature.
