B.T.Express

 

American Singer Barbara Joyce Lomas was part of the Brooklyn based music group B.T.Express and wore a denim vest on promo pictures from 1975. Found in the WWW

Not Barbara Joyce with denim vest but the band wears lot of denim in this tv appearance:

and maybe we have a dancing lady here with denim vest in the audiance of a American tv show:

Harmony 5

 

Harmony 5 seems to have been a short lived French music group, that tried to get a slot for France on the European Song Contest in 1976. I was glad to see a black colored woman with blue jean vest as part of the group, but sorry, I wasn't able to find out her name. Found in the WWW

I think it's not the blue jean vest she wore in this tv appearance from 1976:

Michèle Richard

I also found a photo together with duett partner Renée Martel, where both ladies seem to wear denim vest while being on stage. But it was only available low resoluted.

Renée Martel also wore a denim vest in a short sequence of a private 8mm loop:

Blaupunkt woman

 

I found this blonde lady in an advertise for BLAUPUNKT television devices from Germany around 1975. I'm sure she wears a blue jean vest. 

She appeared also to illustrate the way, a video recorder works. You can record one program and watch another program at the same time and later you can watch the recorded broadcast.

 

Both advertises were found here: https://www.hifi-archiv.info/

But first I met the blonde woman with the blue jean vest in an magazine advertise for BLAUPUNKT from a Hong Kong magazine, published 1976. Too bad that the resolution isn't better.
