Two pairs make 'em we're told (8)
I believe the answer is:
foursome
'two pairs make 'em we're told' is the definition.
(two pairs make four)
This is the entire clue.
(Other definitions for foursome that I've seen before include "The Beatles, for example" , "Quartet" , "Golfing group, perhaps" , "golf match" , "In game" .)
