"Surf's Up"

I recently found a note from last month that I forgot to write about here.  In the Beach Boys' Instagram stories, I'd heard a clip of "Surf's Up," and I realized that in the first section (roughly until ~1:36), the bass plays mostly on the up-beats, perhaps in order to emphasize the "up" in the title phrase.  Here's the notation for the first verse (with the standard disclaimer that I may have something wrong):

Aside from the last two measures, the bass part in the second verse is the same.
