Dionne Warwick is usually associated with ""I Say a Little Prayer" because of her long association with Burt Bacharach and Hal David. But the First Lady of Soul did quite a job with this song herself. Interestingly it was not originally seen as a potential hit tune.
Here's some of the back-story on this great tune, courtesy of Wikipedia: "Intended by lyricist Hal David to convey a woman's concern for her beau who's serving in Vietnam, "I Say a Little Prayer" was recorded by Dionne Warwick in a 9 April 1966 session. Although Bacharach's recordings with Warwick typically took no more than three takes (often only taking one), Bacharach did ten takes on "I Say a Little Prayer" and still disliked the completed track feeling it rushed. The track went unreleased until September 1967 when it was introduced on the album The Windows of the World which largely consisted of older material; it was Scepter Records owner Florence Greenberg rather than Bacharach who wanted "I Say a Little Prayer" added to that album."
Aretha's version came out a year later. It also hit the top ten on the US Rhythm and Blues charts. This is a terrific video that does justice to her beauty and talents. Which version is better? I'd just as soon listen and not judge.
