"Across the Border"

I listened to Out of the Blue yester-day and noticed a small connection between the lyrics and chord progression in "Across the Border" that I think I'd been dimly aware of before.  Under the line "I gotta move down the line" in the first verse, the chord progression is A minor | G major | F major, so there's a musical representation of "mov[ing] down" (because the chords descend) and, in a way, even of "the line" (because it's a conjunct progression).

About a month ago, I figured out the rest of the chords for "Across the Border."  While doing so, I noticed a nod to Chuck Berry's "Let It Rock."  The first line of the first verse of "Across the Border" is "In the heat of the day many miles away," which is quite similar to the first line of "Let It Rock":  "In the heat of the day down in Mobile, Alabama."  Obviously, the phrase "in the heat of the day" is exactly the same; more generally, "many miles away" refers to a location in the same way that "Mobile, Alabama" does.

I think it's also worth mentioning that Jeff Lynne later recorded a cover of "Let It Rock" on his Long Wave album.
