I need to make a correction and a clarification to my post concerning the lack of a tonic triad in "She's Gone." While it's true there are no authentic cadences, and there are no root position tonic triads, the second chord of the verse is a first inversion I chord (I6, or "E/G#" before the modulation), a passing chord from IV to ii. The same bass motion in "I'm Just a Kid" uses IV, iii, and ii.
I'd also like to mention that the "V sussy" sound is more accurately described as an A chord with a B in the bass ("A/B"). This is a sus7 type sound, yes, but its voicing and (non)resolution (the A triad moves up to a B triad in parallel motion) make the "A over B" label much more descriptive and accurate. And it's easy to play on the guitar.
And I just learned that "I'm Just a Kid" was the B-side for "She's Gone." I am pleased by this.
