British love meat, visiting Alabama, more than anything else (5,3)
I believe the answer is:
above all
'more than anything else' is the definition.
(I've seen this before)
'british love meat visiting alabama' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'love' becomes 'o' (In tennis, 'love' means 'zero').
'meat' becomes 'veal' (veal is a kind of meat**).
'visiting' means one lot of letters goes inside another.
'alabama' becomes 'al'.
'b'+'o'+'veal'='boveal'
'boveal' going inside 'al' is 'ABOVE ALL'.
(Other definitions for above all that I've seen before include "What 18 [EVEREST] is" , "primarily" , "Hamlet : 'This . . . . . . . ., to thine own self be true'" , "Notably" , "Like the managing director" .)
