Fly northwards with love and dance (5)
I believe the answer is:
tango
'dance' is the definition.
(I know that tango is a type of dance)
'fly northwards with love' is the wordplay.
'fly' becomes 'gnat' (type of insect).
'northwards' is a reversal indicator (in a down clue, letters go up or 'north').
'with' is a charade indicator (letters next to each other).
'love' becomes 'o' (love means zero in tennis).
'gnat' back-to-front is 'tang'.
'tang'+'o'='TANGO'
'and' is the link.
(Other definitions for tango that I've seen before include "Dramatic ballroom dance from Argentina" , "something seen in ballroom?" , "One from Argentina" , "Colourful dance from Argentina" , "Tonga (anag.)" .)
