Singer in pub, Italian individual (8)
I believe the answer is:
baritone
'singer' is the definition.
(baritone is a kind of singer)
'pub italian individual' is the wordplay.
'pub' becomes 'bar' (both are drinking establishments).
'italian' becomes 'it' (abbreviation for Italian).
'individual' becomes 'one' (an individual is one person).
'bar'+'it'+'one'='BARITONE'
'in' acts as a link.
(Other definitions for baritone that I've seen before include "solo voice" , "One who can sing" , "Male singer between tenor and bass" , "Male voice with deep register" , "Second lowest male singing voice" .)
