They have a very large band including a lot of wind instruments, and they really have fun with it. (Spoiler alert) they've taken to playing Sapphire Bullets of Pure Love in reverse, filming it live, then playing that recording in reverse for the audience (post-intermission).
I also enjoyed that they introduced Birdhouse with "Please rise for the They Might Be Giants national anthem."
Isn't that, like, everything? The first time I saw them it was because they were here, it was affordable, and I dug that Malcom in the Middle song, so why not? The second time was just because they're fun. There will be a next time and it will again be just because they're fun.
And I'm still not sure I could name another of their songs.
No band, just the two of them. Plus the metronome, and some prerecorded backup here and there.
