“I Heard it Through the Grapevine” is such a great song it was a big hit twice – in 1967 for Gladys Knight & the Pips and in 1968 for Marvin Gaye (which was a #1). You may also remember the Creedence Clearwater Revival version and the California Raisins commercial. The first recording was actually by Smokey Robinson and the Miracles in 1966 but was not released as a single.
