Crazy; what a year ... seized the opportunity! (4,3)

I believe the answer is:

made hay

'seized the opportunity' is the definition.
(I've seen this in another clue)

'crazy what a year' is the wordplay.
'crazy' becomes 'mad' (synonyms).
'what' becomes 'eh' (sound used to ask 'what?' or 'pardon?').
'year' becomes 'y'.
'mad'+'eh'+'a'+'y'='MADE HAY'

(Another definition for made hay that I've seen is " Seized an opportunity".)

I've seen this clue in The Telegraph.
