The song "I Heard It Through the Grapevine" is not originally by Joe Cocker. It was written by Norman Whitfield and Barrett Strong and made famous by Marvin Gaye in 1968. However, Joe Cocker did cover the song in 1980 with his own rendition. The lyrics describe a person who learns through rumors or gossip ("through the grapevine") that their partner is planning to leave them for someone else. The protagonist is devastated by this revelation, as they believed that they loved their partner more than anyone else. The news comes as a surprise, and they feel they've been left in the dark, wondering why their partner didn't tell them directly. The chorus repeats the phrase "heard it through the grapevine," emphasizing the method in which the protagonist has learned about the impending breakup. The line "and I'm just about to lose my mind" reflects the emotional turmoil and heartbreak they are experiencing. The lyrics also touch upon the societal advice of not fully trusting what you hear, as people may spread falsehoods or exaggerations. The protagonist is confused and seeks clarification from their partner, questioning whether they plan to leave them for the other person they knew before. Overall, "I Heard It Through the Grapevine" expresses the pain of discovering betrayal and the anguish of losing a loved one, as well as the confusion and desire for clarity in the midst of rumors and speculation.
