Change in a fellow (3)

I believe the answer is:

ian

'fellow' is the definition.
(man's name)

'change in a' is the wordplay.
'change' indicates an anagram.
'in'+'a'='ina'
'ina' with letters rearranged gives 'IAN'.

(Other definitions for ian that I've seen before include "... Fleming, author of the Bond books" , "- Fleming (James Bond)" , "- - Wallace (baritone)" , "- McEwan, Eng. writer" , ". . . Botham, . . . Woosnam" .)

I've seen this clue in the Evening Standard.
