The quote highlights the unique ability of a character named Reb to sing a wide variety of songs, unlike the iconic figures of Walt Whitman and Billie Holiday who are known for their specific musical contributions. While Whitman is celebrated for his connection to life and the human experience, and Holiday is recognized for her emotional depth in blues, Reb's talent seems to encompass all genres and styles, making him an extraordinary figure in the realm of song.

The mention of Reb responding to a casual inquiry with a song lyric illustrates his profound connection to music as a means of expression. It shows that for him, singing is not just a talent but an intrinsic part of his identity, allowing him to convey his emotions and state of mind through familiar melodies and lyrics. This emphasizes the power of music in communicating feelings and connecting with others.
