Paul from San Francisco, CaThe description above is much too ingenuous... this is a song which talks about "getting a little cash and putting it in the market" in 1927! Not exactly the brightest of ideas.
The song is written to convey the absurd cheeriness and optimism of the late 1920s (and does an amazing job of doing so, I might add). Dramatic irony at its finest.
Holland-Dozier-Holland originally wrote "Where Did Our Love Go" with The Marvelettes in mind, but they turned it down. Marvelettes lead singer Gladys Horton sang in a lower key than Diana Ross, so when The Supremes came to record the tune, Ross was forced to sing in a lower, breathier style than she was used to.
