Early in 1997, John held a 50th birthday bash, costumed as Louis XIV of France, with 500 good friends. John's optimum-charting single was a collaboration with Dionne Warwick, Gladys Knight, and Stevie Wonder named "That's What Friends Are For". The tune was introduced as the direct single for her debut whole-size job, which is her debut mixtape, titled From a Planet Called Harlem.
