Both Marvin Gaye and Valerie Simpson gave different stories on how the production of Terrell's and Gaye's third album together, "Easy", went about. According to reports, Terrell had gotten so ill from her operations that she could not record, and Motown opted to have Valerie Simpson sub in for Terrell, a report that was repeated in the book "Marvin Gaye: What's Going On and the Last Days of the Motown Sound". Gaye would later say the move was "another moneymaking scheme on BG's [Berry Gordy's] part". Valerie Simpson, on the other hand, stated that the ailing Terrell was brought into the studio when she was strong enough to record over Simpson's guide vocals, insisting Terrell had sung on the album. "Easy" produced the singles "Good Lovin' Ain't Easy to Come By", "What You Gave Me", "California Soul" and the UK top ten hit, "The Onion Song". Late in 1969, Terrell made her final public appearance at the Apollo Theater where Marvin Gaye was performing. As soon as Gaye spotted Terrell, he rushed to her side and the duo began singing "You're All I Need to Get By" together. They were given a standing ovation by the public.
