One responsible for standards in cabbage and beer (4,6)
I believe the answer is:
cole porter
'one responsible for standards' is the definition.
(composer of many songs which became standards)
'cabbage and beer' is the wordplay.
'cabbage' becomes 'cole' (cole is a kind of cabbage).
'and' says to put letters next to each other.
'beer' becomes 'porter' (I've seen this in other clues).
'cole'+'porter'='COLE PORTER'
'in' acts as a link.
(Other definitions for cole porter that I've seen before include "Man responsible for standards" , "US man of note" , "Broadway composer" , "Let's Do It songwriter" .)
