If you will raise tons, we will perform (2,2,4)

I believe the answer is:
as it were
'will perform' is the definition.
I can't judge whether this definition defines the answer.
'if you will raise tons we' is the wordplay.
I cannot quite see how this works, but
'tons' could be 't' and 't' is found in the answer.
'we' is within the answer.
an anagram of 'raise' is 'asire' which is present in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for as it were that I've seen before include "In a manner of speaking" , "Seemingly" , "you might say" , "In a kind of way" , "Historically ungrammatical" .)
