 The session featuring Gaye led to an argument between the producer and singer . Whitfield wanted Gaye to perform the song in a higher key than his normal range , a move that had worked on David Ruffin during the recording of the Temptations ' hit , " Ain 't Too Proud to Beg " . The mixture of Gaye 's raspy vocals and the Andantes ' sweeter harmonies , made Whitfield confident that he had a hit ; however , despite approval from Motown 's Quality Control Department , Gordy blocked the release .
