Outline of Elvis Concerto's uplifting but hit-and-miss (7)
I believe the answer is:
stencil
'outline' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for stencil that I've seen before include "It's perforated for ink or paint to pass through" , "Cut-out pattern for applying paint" , "Cut-out for applying ink" , "decoration? One must be cut out for it" , "outline" .)
