Tempo new to large town (7)
I believe the answer is:
preston
'large town' is the definition.
'tempo new' is the wordplay.
'tempo' becomes 'presto' (musical tempo).
'new' becomes 'n'.
'presto'+'n'='PRESTON'
'to' is the link.
(Other definitions for preston that I've seen before include "Town in Lancashire" , "English city" , "Town on the Ribble" , "city (as of 2002)" , "City in Lancashire" .)
