Band created, we hear, for a pub employee (7)
I believe the answer is:
barmaid
'a pub employee' is the definition.
(I've seen this before)
'band created we hear' is the wordplay.
'band' becomes 'bar' (both can mean a strip or line).
'created' becomes 'made' (making is a kind of creating).
'we hear' shows a homophone (sound like).
'made' is a homophone of 'maid'.
'bar'+'maid'='BARMAID'
'for' acts as a link.
(Other definitions for barmaid that I've seen before include "Pub worker" , "Local girl" , "She serves drinks" , "Female serving drinks" , "Pub employee" .)
