Apparently, according to Joni Mitchell in Woodstock.
I’ve heard this song approximately a billion times (mostly by Crosby, Stills and Nash) and never once did I notice this phrase. I assumed it had something to do with the “devil’s bargain” and never paid any attention to it.
I’m usually a very lyrically aware person, and how I missed this FOREVER is astounding to me.
Any other lyrics that jumped out at you after a long period?
I didn’t know that at the time, but some years later it clicked. Not the “I don’t like Mondays” line but “And daddy doesn’t understand it, / He always said she was as good as gold,” because I remembered Spencer’s father saying that she was “good as gold.” Funny what sticks in your head.
I never heard the billion year old carbon line either, and know that I know I can’t remember what I imagined it was.
I was dumbfounded recently to learn that Kate Bush was singing Jeux Sans Frontieres in Peter Gabriel’s Games Without Frontiers. I thought it was Gabriel singing she’s so popular high-pitched.
In the Matthews Southern Comfort version (the first one I heard) they omit the line completely.
We are stardust
We are golden
And we’ve got to get ourselves back to the garden
As an aside - I like that version. It always gave me a bit of a “sci-fi” feel. It’s about lost traveling aliens, trying to find their way home, rather than dirty hippies at a badly-organized rock concert.
