"You Can Never Go Home"

Yester-day, I figured out the chords for "You Can Never Go Home" and noticed some significance with the tonic chord and note.  The song is in D major, so D is the tonic note and the musical "home."  In the two instances of the lines "Memories can never take you back home sweet home / You can never go home anymore" (at ~0:49 and ~3:43), the first "home" is sung to a G above a G major, the second to a pair of F#s above a D major, and the third to a D above a G major.  Some of these may give a hint of being musically at home either because "home" is sung above the tonic chord (the second "home") or because it's sung to the tonic note (the third "home"), but there isn't a fully realized homecoming with "home" sung to a D note above a D major.  Musically, then, there's the same sentiment that's in the lyrics:  "You can never go home."
