"Coal Miner's Daughter" singer (4)
I believe the answer is:
lynn
'coal miner's daughter singer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lynn that I've seen before include "See 14" , "Vera --; King's --" , "King's --, Norfolk town" , "Dame Vera -, the 'Forces' sweetheart'" , "Singing dame" .)
