Cry out for the old record format (4)
I believe the answer is:
yelp
'cry out' is the definition.
'the old record format' is the wordplay.
'the old' becomes 'ye'.
'record format' becomes 'lp' (abbreviation for long play record).
'ye'+'lp'='YELP'
'for' is the link.
(Other definitions for yelp that I've seen before include "Express discomfort" , "bark sharply" , "Shrill short cry of dog" , "Barking" , "Short sharp cry or bark" .)
