Two of my favourite song writers have revealed themselves as astronomy nerds in love songs.
Frank Black in “Sir Rockaby” (1994):
How many stars girl
Can you both count
And then classify?
I’m standing here in this big swirl
Singing this lullaby
Robert Schneider of the Apples in Stereo in “7 Stars” (2007):
Seven stars in the sky
You’re feeling sociable
Silver stars in your eyes
You feel emotional
And you don’t even know my name
And I know every constellation
