I was thinking about "Drive My Car" this morning, and I realized that under the line "But you can do something in between," the drums start lending some emphasis to the off-beats, something like:
This change in the rhythm is especially conspicuous since the cowbell, which had been playing on each downbeat, drops out.
I may be making too much of this, but this emphasis on the off-beats sort of complements the "in between" in the lyric above.
