Nope, not a wizard. Unless you count mathematical wizardry.

I started out thinking that the theme was 'jams from shows with big bustouts' which was certainly relevant to the Mexico shows. I was checking the shows with the biggest bustouts: FYF, Skin it Back, Curtain With, etc.

But then I read @uctweezer 's comment: Surprised no one has solved this yet – this is a juicy ass hint [insert retail changing room joke here] for anyone who has been following Phish closely of late and has already found one of the clips

I figured there was probably a closer tie to the Mexico bustouts, looked at the setlist notes, and started searching for shows on the other side of these bustouts. I got the 2003 Twist first and then the others weren't hard.

I feel like I've been lucky on my last few wins to be one of the first people to understand the hint AND to have a little bit of free time to search.
