Everything I’ve Got Belongs to You is a show tune written by Richard Rodgers and Lorenz Hart for the 1942 musical By Jupiter, where it was introduced by Ray Bolger and Benay Venuta. The song has since become a jazz standard, with notable recordings by Ella Fitzgerald on her Rodgers & Hart Songbook (1956) and Blossom Dearie on the 1957 album Blossom Dearie. It’s often performed as a vocal jazz number and appears in various live and studio releases, highlighting Hart’s witty, assertive lyrics set to Rodgers’ memorable melody. In short, it’s a classic 1940s show tune that crossed into the jazz repertoire and remains widely covered.
