Producer Norman Whitfield recorded "I Heard It Through the Grapevine" with various Motown artists. The first known recording is with the Miracles on August 6, 1966, though there may also have been a recording with the Isley Brothers, or at least Whitfield intended to record it with them; however a track has not turned up - some Motown historians believe that a session may have been scheduled but cancelled. The Miracles' version was not released as a single due to Berry Gordy's veto during Motown's weekly quality control meetings; Gordy advised Whitfield and Strong to create a stronger single. The Miracles version later appeared on their 1968 Special Occasion album, and a slightly different take, possibly from the same session but unreleased, appeared on the 1998 compilation album, Motown Sings Motown Treasures.  Marvin Gaye's version was recorded in spring 1967, and is the second known recording, though was also rejected by Gordy as a single, and would also later go onto an album, In the Groove. The third recording was in 1967 with Gladys Knight and the Pips in a new, faster arrangement. Gordy accepted the new arrangement and the Gladys Knight version was released as a single in September 1967, reaching number 2 in the charts. When Gaye's album with his version of Grapevine was released in August 1968, radio disc jockeys were playing the song, so Gordy had it released as a single in October, and it went to number one in December.  In 1968, Bobby Taylor & the Vancouvers recorded a version for their debut album based on Gladys' recent hit; however, after hearing the Marvin Gaye version, they felt they'd made the wrong choice. In 1969, Whitfield produced a version for the Temptations "psychedelic soul" album, Cloud Nine, in which he "brought compelling percussion to the fore, and relegated the piano well into the wings". In 1971, the Undisputed Truth recorded the song in a Marvin-styled version as did Bettye Lavette on her 1982 Motown album, Tell Me a Lie.
