Benny's on record as a nice chap (7)
I believe the answer is:
goodman
'benny's' is the definition.
(musician Benny Goodman is an example)
'nice chap' is the wordplay.
'nice' becomes 'good' (similar in meaning).
'chap' becomes 'man' (chap can mean a man).
'good'+'man'='GOODMAN'
'on record as a' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for goodman that I've seen before include "Jazz musician" , "Benny ___ , 'King of Swing'" , "jazz player" .)
