The first Richie Family ( and there were a lot of them) was actually the Sweethearts of Sigma ( Barbara Ingram, Carla Benson, Yvette Benton). When they didn't want to tour to
promote "Brazil", the producer formed a new group made up of Cassandra Wooten, Gwen Oliver (from Honey and the Bees) and another singer.
Norman Harris also produced 2 albums for Eddie Kendricks on Tamla- "He's A Friend" and "Goin' Up In Smoke".
Elton John worked with Thom Bell on the "Thom Bell Sessions" EP.
