Bard composed, crossing into city (8)
I believe the answer is:
bradford
'city' is the definition.
(I've seen this before)
'bard composed crossing' is the wordplay.
'composed' is an anagram indicator.
'crossing' becomes 'ford' (ford is a kind of crossing).
'bard' anagrammed gives 'brad'.
'brad'+'ford'='BRADFORD'
'into' acts as a link.
(Other definitions for bradford that I've seen before include "W. Yorkshire city" , "West Yorkshire city" , "industrial city" , "W Yorks city" , "northern city" .)
