Hi all,
As I lay in bed last night, my mind was filled with this thought: were there any Motown stars who had number one hits on Billboard chart as a single performer and as a member of a group and as a duet? I came up with three, but I wonder if there were more?

Diana Ross - Group: Supremes, Duet: Lionel Richie, and solo
Lionel Richie - Group: Commodores, Duet: Diana Ross, and solo
Stevie Wonder - Group: We Are the World ensemble...I know this is stretching it, but they are a group and Lionel and Diana fit here also, Duet: McCartney and solo
