"The Spell That You Cast" is a song by Elvis Costello, released in 1991. The lyrics depict a person who is under the influence of a spell cast by their lover. The protagonist initially expresses that the spell seems to be wearing off quickly, and they are unsure if they can handle it. They wonder if their lover has found someone else who pleases them more, causing insecurity and jealousy. As the song progresses, the protagonist pleads for their lover to come back or at least inform them about their whereabouts. They admit that they are not typically a jealous person, but the way others look at their lover hypnotizes them. The protagonist expresses their deep love and sadness, knowing that they will miss their lover desperately. The chorus, "Jimmy come quickly 'cos I feel quite sickly, you're like a gangster's Molly with a cannonade volley," adds a touch of humor to the song. It suggests that the protagonist is feeling unwell and needs someone (possibly a friend named Jimmy) to help them through their emotional turmoil. Overall, "The Spell That You Cast" portrays the emotional vulnerability and insecurity one experiences when they believe their lover's attention and affection are fading. The song combines elements of longing, self-doubt, and desperation for the lover's return.
