 Marvin and Tammy's collaborators, Valerie Ashford and Nick Simpson. Nick Ashford, rather, and Valerie Simpson said it turned around backwards. You know what I'm talking about. Ashford and Simpson. They were the collaborators with Tammy and Marvin, and what an amazing job they did. Of course, Ashford and Simpson wrote a lot of songs for a number of artists on the Motown label. But if I'm going to mention Marvin and Tammy, I've got to mention Val and Nick as well, Ashford and Simpson, as their brilliant, brilliant collaborators.
