Yes, the fourth is still a few days away, but the upcoming celebration was a part of the thought behind our current theme of fireworks. July 4th ... there may be reunion somewhere in your fireworks, but I'll make no further attempt at a conceit/an effort to combine these two themes. Just a fire-related thought or two to get us rolling ...
Things in the sky above use are naturally spacy (as in ether = air?). You look up. You see the stars. You see lights. You see beyond. And it's often even more awesome/beautiful when there are human-made colors and lights above your head. For example, airplanes, satellites and fireworks.
This is one of those songs that embodies the qualities of the air/the sky: As in the lyrics, as in the stars above - there is a spiral to the guitar, to the music. The song makes use of a repetition that seems to embody the motion of the stars, to lights in the sky: to the continuity of "earth, sky, sea and rain". To me, it calls to mind the roman candles of its lyrics, lights that spiral and spin through the heavens and enthrall us from below.
For some reason, this song also called to mind a realization that there is a similar effect in Midnight Mile off of Sticky Fingers - part of it is that guitar, part of it is the vocal style and part of it is the ethereal lyrics. Cf:
