Why pull Halley's like that? It just makes no sense.

If you're asking why they played it all, I have no idea.

If you're asking why they slammed into 46 Days instead of jamming Halleys, I'd guess because it sounded awesome and the subsequent 46 Days jam was better than all but 2, maybe 3 Halleys jams ever, so I have to feel like it was the right choice.

As megafans, we want every song to be jammed out, and if not, at least a little something different about it. Be happy Trey closes his eyes a lot when the jams start getting deep, because if he was watching the crowd more they'd probably jam less. Unless a jams really upbeat, a lot of people are going to be talking through it. People who have never heard of the band before, people who have been to 300 shows. Whatever.

They'd be crazy to not have any idea that no matter our protests to the contrary, the vast majority of the crowd is more engaged with the chorus to Sample In A Jar than the delicately layered otherworldly textures of deep improv

If you're in a band, that's going to mean something to you. And I feel like Phish 3.0 has done a great job of balancing competing interests.
