Hero worship? Puck does have a go, after taking note (8)
I believe the answer is:
idolatry
'hero worship?' is the definition.
(worshipping an idol)
'puck does have a go after taking note' is the wordplay.
'puck does' becomes 'ido' (I can't justify this - if you can you should believe this answer much more).
'have a go' becomes 'try' (I've seen this in another clue).
'after taking' indicates putting letters inside.
'note' becomes 'la' (musical note as in do-re-mi).
'ido'+'try'='idotry'
'idotry' placed around 'la' is 'IDOLATRY'.
(Other definitions for idolatry that I've seen before include "Worship of carved images" , "Adroitly (anag.)" , "Dilatory way of worshipping" , "reverence" , "Graven image worship" .)
