"La Vie en Rose" singer Edith (4)
I believe the answer is:
piaf
'la vie en rose singer edith' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for piaf that I've seen before include "Edith -, Fr. cabaret singer (Non, je ne regrette rien)" , "See 6 Down" , "French singer, the Little Sparrow, d. 1963" , "French singer who regretted nothing" , "Edith -, twentieth century French cabaret singer" .)
