Heed revised note appended to catalogue (6,2)

Ross

I believe the answer is:

listen to

'heed' is the definition.
(synonyms)

'revised note appended to catalogue' is the wordplay.
'revised' indicates anagramming the letters.
'appended to' is a charade indicator (letters next to each other).
'catalogue' becomes 'list' (I've seen this in another clue).
'note' is an anagram of 'ento'.
'ento' put after 'list' is 'LISTEN TO'.

I've seen this clue in The Guardian.
