"It Takes Two" #14 3/4/1967

Marvin Gaye had a number of duets over the years with Mary Wells, Diana Ross, and most notably with Tammi Terrell. Here's a Top 5 R&B duet he did with Kim Weston and co-written by her then-husband Mickey Stevenson, who helped put together the Funk Brothers, the house band at Motown. Kim and Mickey had already left the label in a dispute over her royalties by the time this was released as a single.
