The quote reflects on the anonymity of the musician Steve Miller, suggesting that despite his fame, few people can accurately identify him. It humorously proposes that he could be anywhere, even performing a recognizable song, without being recognized by the average person. This points to a disconnect between celebrity status and personal recognition.
Furthermore, the imagery of Miller as a "big blue space-horse" with "orange space-flames" emphasizes the surreal and absurd nature of celebrity culture. It suggests that the essence of a celebrity can become detached from their actual identity, leading to a whimsical interpretation that combines both humor and critique of how society perceives public figures.
