I always thought of Led Zeppelin's "Stairway to Heaven" as an anti-communist song about the Iron curtain which at the time(1971) was very strong, especially with this stanza,

There's a feeling I get when I look to the west
And my spirit is crying for leaving
In my thoughts I have seen rings of smoke through the trees
And the voices of those who stand looking

JMO, but the above stanza describes thoughts of a person contemplating to get over the Iron curtain.

[Arthur Wildfire! March]

I don't know about themes, but Led Zepplin's Kashmire was a song I searched out for years with utter persistance back in my days before politics. Listening to Kashmire makes me think about the sands of history. The loss of a once-great civilization. The foolish quest for petty, fleeting glory. I feel wisdom in that song.

As for Buying a Stairway to Heavan, it makes people think about Heavan. It makes people wonder about some lady going to make a salvation purchase at a church as though it were a discount store. I stresses the importance of that purchase, and taunts those who throw money at it rather than their souls.

[Skywalk]

Actually, there's a more explicit reference to escaping over the Berlin Wall in David Bowie's classic "We Can be heroes"

[Knitting A Conundrum]

I always thought that bit about looking to the west was an allusion to Lord of the Rings, myself...but yours is a nice image.
