That was recalled on Tammi's "Unsung" last year! More evidences to why I don't believe Tammi was completely absent from "Easy"! Marvin was performing their duets with Carla Thomas! Tammi kept it together until they began "Your All I Need", when Tammi got up and started singing! Marvin saw Tammi and left Carla on the stage and did the song with Tammi instead, to a standing ovation!
