After deciding this, I listened to the Surfin' Safari/Surfin' U.S.A. re-issue (the first Beach Boys albums seemed like the place to go), and I figured out a few parts in the following days. One of the parts I figured out was the bass part for "County Fair," and since it was really easy, I even notated it:
Of course, there's the disclaimer that I might be wrong about this, but I'm pretty sure that what I have is accurate.
If I'm not mistaken, the guitar part consists of only one phrase:
When I notated the bass part, I noticed that one section has ascending phrases for almost every measure (arpeggiating G6 and D6 chords). Like I mentioned in this post, the organ part there quotes "Over the Waves." Since the bass part beneath that quotation looks like waves when notated, I'm wondering if it's meant to be something of a musical joke.
