The history of this group is incredibly complex, and I prefer not to get too wordy on my posts so I'll leave it at this. While the Blossoms had a number of personnel changes since their 50's inception, the Blossoms who are most well known (appeared on the Shindig TV show) included Gloria Jones and (lead singer) Darlene Love (who also recorded with Phil Spector not only under her own name but as a backing singer and also a lead on cuts by The Crystals (who were actually the Blossoms under another name).
This track was recorded shortly after Gloria Jones left for her solo career.
Darlene Love went on singing (which she does to this day) and has added acting to her already impressive resume.
I find this track to be the peak of her glories. Girl group soul simply doesn't get any better. Also note that this is another superb composition by Van McCoy.
