Jackson sang with one of the best doo wop groups, the Dell-Vikings, for a while in the late '50s (although he doesn't appear on their hit singles). Spotted by Scepter Records while performing with Jackie Wilson's Revue, he started recording for the label in 1961. As was the case with labelmates Dionne Warwick and the Shirelles, Jackson's early-'60s arrangements blended pop, R&B, and New York-session professionalism. Like Warwick, Jackson was one of the first singers to successfully record Bacharach-David material; one of his best singles, "I Keep Forgettin'" (1962), was written and produced by Leiber-Stoller. Jackson had success with some duets with Maxine Brown in the mid-'60s, but he left Wand in 1967 for Motown, at the urging of Smokey Robinson. Jackson was lost in the shuffle during his four years at Motown, although he remains a favorite on England's "Northern soul" scene. ~ Richie Unterberger, Rovi
