In more or less chaotic stage parts! (5)
I believe the answer is:
roles
'stage parts' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for roles that I've seen before include "Dramatic parts" , "Theatrical parts" , "Parts in plays" , "Parts in a play" , "Actors' parts" .)
