Test this funky old track in record we hear (4,7)
I believe the answer is:
oral history
'record we hear' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'test this funky old track' is the wordplay.
'test' becomes 'oral' (oral is a type of examination).
'funky' indicates anagramming the letters (an unusual form of the letters).
'old' becomes 'o' (abbreviation).
'track' becomes 'ry' (abbreviation for railway).
'this' with letters rearranged gives 'hist'.
'oral'+'hist'+'o'+'ry'='ORAL HISTORY'
'in' is the link.
Can you help me to learn more?
(Another definition for oral history that I've seen is " knowledge of the past".)
