Show’s opening? That’s my cue to meet playwright (5)
I believe the answer is:
simon
'playwright' is the definition.
(I know that Simon is a playwright)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for simon that I've seen before include "- and Garfunkel" , "Simple pieman" , "Fellow" , "Harris and Coveney" , "Sir -- Rattle, conductor" .)
