A gig for some of the banjo boys? (3)
I believe the answer is:
job
'a gig' is the definition.
(thesaurus)
'some of the banjo boys?' is the wordplay.
'some of' indicates a hidden word.
'JOB' can be found hidden inside 'banjo boys'.
'for' is the link.
(Other definitions for job that I've seen before include "Patient figure in the Bible - task" , "'Task, chore (3)'" , "Task; paid position" , "Book; task" , "Personification of patience" .)
