Made during a concert with, say, Robin Williams essentially entering profession (10)
I believe the answer is:
livelihood
'profession' is the definition.
(thesaurus)
'made during a concert with say robin williams essentially entering' is the wordplay.
I cannot really understand how this works, but
'robin' could be 'hood' (I've seen this in other clues) and 'hood' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for livelihood that I've seen before include "Occupation" , "source of income" .)
