B Positive Theme Song Lyrics
Behind the Tune: Meaning & Story
The theme song for B Positive is a rare example of a sitcom intro that evolved significantly during its broadcast run. Originally composed with a bluesy, soulful feel by legendary musician Keb’ Mo’, the song underwent a stylistic shift in the second season. From the third episode of Season 2 onward, the vocals were taken over by series lead Annaleigh Ashford, reflecting the show’s transition from a narrow focus on kidney donation to a broader ensemble comedy set in an assisted living facility.
The lyrics emphasize the “circular” nature of altruism—the idea that giving to others directly enriches one’s own life. The title itself is a clever triple entendre: it refers to the blood type needed for the transplant (B-Positive), the protagonist’s name (Drew), and the optimistic mindset required to face life-threatening health challenges.
Created by Marco Pennette, the show used this upbeat track to balance the heavy subject matter of organ failure with the lighthearted, resilient spirit of its characters, Drew and Gina.
