Great performers who put surf on file? (6,8)

I believe the answer is:

record breakers

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

'great performers who put' is the definition.
I can't judge whether this definition defines the answer.

'surf on file?' is the wordplay.
'surf' becomes 'breakers' (synonyms).
'on' is a charade indicator (letters next to each other).
'file?' becomes 'record' (file is a kind of record).
'breakers' put after 'record' is 'RECORD-BREAKERS'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
