"Good Lovin' Ain't Easy to Come By" is a duet released in 1969 on the Tamla label by renowned singers Marvin Gaye and Tammi Terrell. The first release off the duo's third album, Easy, it has been hugely debated whether or not an ailing Terrell, who was dying from a brain tumor, was on the track or if the song's co-writer, Valerie Simpson, subbed for Terrell. The recording was featured in the film The Boys in the Band.
