Do you notice the chord inversions played in Over the Hills & far Away by Jimmy Page/Led Zeppelin?

I really noticed the main intro chord progression's tonic is inverted from the 3rd and 5th position to the 9th and 7th positions. Both being major chord inversions keeping with the resonant introductory theme from the guitar.

I am writing a tutorial regarding the use of chord inversions and I posit that inversions are the secret to keeping a chord progression exciting to the listener and player alike. It allows you to hear or play the same general idea or pep it up without abandoning the musical thought or "groove" as it is. I think Over The Hills is a great example of it's usage in a rock song. Jimmy Page does this in many other songs too.

Can you hear the chord inversions when he plays them, or do you just jam the song because it ROCKS! And, do you know of other songs that chord inversions play a big part of the arrangement?
