Is he a jazzy type? If the cap fits . . . (6)

I believe the answer is:

hepcat

I'm a little stuck... Click here to teach me more about this clue!

'is he a jazzy type?' is the definition.
The definition suggests a singular noun which matches the answer.

'the cap fits' is the wordplay.
'fits' indicates an anagram.
'the'+'cap'='thecap'
'thecap' with letters rearranged gives 'HEPCAT'.

'if' is the link.

Can you help me to learn more?

(Other definitions for hepcat that I've seen before include "one with it" , "Jazz or swing fan (1940s' slang)" , "Old jazz fan" , "trendy no longer" .)

I've seen this clue in The Globe and Mail.
