K Nicola Dyes interviewed Margaret in 2013:

Margaret Cox has been one of the hardest working women on the Minneapolis music scene for nearly 40 years. She was born in Kenitra, Morocco and her family moved to Minneapolis when she was 7 years old..

Cox found her greatest success when Jesse Johnson recruited her as the lead singer for the group Ta Mara and the Seen in the 1980s (along with band members Oliver Leiber, Gina Fellicetta, Keith Woodson Cox and Jamie Chez). The group found immediate success in 1985 with their first single "Everybody Dance," a Billboard Top 40 pop hit and Top 5 R&B hit..

Cox independently released a solo album entitled Margie's Little Demo and her band The Legendary Combo (formerly known as Dr. Mambo’s Combo) currently has a longstanding gig Sundays and Mondays at Bunker’s Music Bar and Grill in Minneapolis.
