Sinatra bothered craftsperson (7)
I believe the answer is:
artisan
'craftsperson' is the definition.
(I've seen this in another clue)
'sinatra bothered' is the wordplay.
'bothered' is an anagram indicator.
'sinatra' anagrammed gives 'ARTISAN'.
(Other definitions for artisan that I've seen before include "Skilled worker by hand" , "Skilled manual 17" , "Journeyman" , "Skilled worker at craft or trade" , "one in command of craft?" .)
