What we do know is that Margie was a member of the original Cookies who's biggest hit was the lovely mid-50s classic "In Paradise" for Atlantic. From the Cookies she went on to found The Raelettes (sometimes spelled the Raelets) and spent the mid 1950s to the early 1960s backing and duetting with Ray Charles. This is her "claim to fame." She was depicted in the film Ray and since then has become infinitely more known because of it.
But Margie also had a solo career after parting ways with Ray. While her output wasn't extensive, she did manage to scorch some 45s with her vocal inferno. She was perhaps the greatest soul shouter of all time.
Though Margie didn't put out many solo records, it's still difficult for me to choose my favorite. The record I've chosen to highlight today is "Packin' Up." It's a quick-paced, gospel-charged liberation song, written by Margie. Need a pick-me-up? This is more effective than a triple shot of espresso. Give it a taste.
