The song "Sandy" by John Mayall's Bluesbreakers is about a man who is searching for his lover named Sandy. He is curious about what she does each day and night, and follows her behavior. He knows that she has taken his pendant and it's lying on her breast, but he is frustrated with her actions. He is hurt to see her step inside another man's car, and although he knows he should move on, he can't help but wait for her to come back to him. The lyrics suggest that Sandy may be unfaithful and that the narrator feels like a fool for waiting for her. Ultimately, the song conveys a sense of heartbreak and betrayal.
