Brown has a try at a dance (5)
I believe the answer is:
tango
'a dance' is the definition.
(tango is a kind of dance)
'brown has a try' is the wordplay.
'brown' becomes 'tan' (tan is a kind of brown).
'has' is a charade indicator (letters next to each other).
'a try' becomes 'go' (go is a kind of try).
'tan'+'go'='TANGO'
'at' is the link.
(Other definitions for tango that I've seen before include "One from Argentina" , "Dramatic ballroom dance from Argentina" , "Dramatic dance form Argentina" , "Steps" , "Dance; T (radio comms.)" .)
