From 1966, and the apparently otherwise undistinguished British B-flick Dateline Diamonds, please enjoy the incomparable Kiki Dee...
...before anybody in the colonies had ever heard of her.
The Small Faces come on at the end ; Kiki, looking incredibly mod and adorable, can be seen performing (beginning at approximately the 3:50 mark) and wow.
She's great, is what I mean. Like Dusty Springfield great.
Now that I think of it -- there must have been something in the water back then; how else do you explain all those great Brit white-girl R&B singers?
