There was half a dozen groups either called the Cashmeres or had cashmeres in the group name.
The one we are concerned with (Hubba Hubba, HEM and Ninandy artists) had Eddie Jefferson (Jeff on the acetate), Robert Rennie and as also stated on the label Brown and Busby.
Robb K on Soulful Detroit said "Eddie Gibbs and Don Edwards were also members of the group (I believe, before Eddie Jefferson joined?" That would make 6 members at various points in the brief history of the group, not saying at the same time though.
What is the source of the photo?
