THE SUPREMES: (Singing) My world is empty without you, babe.
RACHEL MARTIN, HOST:
One of the Supreme voices who made this song, "My World," has died. Mary Wilson was a founding member of the Supremes, and she stayed with the group even after Diana Ross had left. NPR's Lauren Onkey, senior director of NPR Music, knew Mary Wilson and worked with her, and she is on the line with us now. Good morning, Lauren.
LAUREN ONKEY, BYLINE: Good morning, Rachel.
MARTIN: You actually interviewed Mary Wilson, I understand, when you worked in the public education program at the Rock & Roll Hall of Fame. Tell us about her.
