Drama not composed willy-nilly (2,6)
I believe the answer is:
at random
'willy-nilly' is the definition.
(I've seen this before)
'drama not composed' is the wordplay.
'composed' is an anagram indicator.
'drama'+'not'='dramanot'
'dramanot' anagrammed gives 'AT RANDOM'.
(Other definitions for at random that I've seen before include "Without method or conscious decision" , "Casually" , "willy-nilly" , "without purpose" , "Indiscriminately" .)
