Small frame BIG sound.
Mireille Mathieu springs to mind…..The late 1960s rebirth version of the modern Edith Piaf sound. Often a quest on TV variety shows (with Topo Gigio) on Saturday and Sunday nights in the UK, even though not many viewers actually knew what she was singing about.
After thought with me thinking back….. Edith, Mireille and Topo do all kinda look alike
