Classic 60's Girl-Group-Pop
This song has some real depth going on the production. We've got piano, organ, and what I'm pretty sure is a vibraphone doubling a lot of the other keyboard parts. There is a standard rock trio of drums, guitar and bass. The brass is made up of at least two trumpets and two trombones. As far as vocals go, Diana Ross is clearly dominant in the mix. It would be another two years before the group's name was changed to Diana Ross & The Supremes, but her voice is the only one you can clearly make out. That's not to say the other ladies aren't doing some great support work. The producers on this track were responsible for so many Motown hits I can't name them all here. I do hope we'll hope to hear more of them later on.
Lyrically the song is a simple plea for a wayward lover to think before cheating again. The voicing is not angry, but instead plaintive, reminding the cheater of the good times, and how much his actions hurt her. It's a little surprising to me how many people song this song, or at least the hook with such joy and abandon. I guess people don't always listen to lyrics. They're probably the same people who think that Isn't She Lovely? makes a good wedding song.
