Went on list, working in Hollywood (10)
I believe the answer is:
tinseltown
'hollywood' is the definition.
(I've seen this before)
'went on list working' is the wordplay.
'working' indicates an anagram.
'went'+'on'+'list'='wentonlist'
'wentonlist' is an anagram of 'TINSELTOWN'.
'in' acts as a link.
(Other definitions for tinseltown that I've seen before include "Name for Hollywood" , "movie industry" , "part of LA" .)
