"What You Gave Me" is a hit duet written and produced by Ashford & Simpson and issued as a single originally by the vocal duo of Marvin Gaye and Tammi Terrell in 1969 on the Tamla label. Recorded in the final throes of the Gaye-Terrell duet recordings, the song became the second single from their album, Easy. As with much of the album, there is debate over who sang with Gaye: Terrell, who was undergoing treatment for brain cancer, or the track's co-writer and co-producer, Valerie Simpson. Cash Box described it as a "finely honed vocal collaboration."
