Admirer and crook go to a dance (8)
I believe the answer is:
fandango
'a dance' is the definition.
(type of dance)
'admirer and crook go' is the wordplay.
'admirer' becomes 'fan' (fan is a kind of admirer).
'crook' indicates anagramming the letters (a crooked or broken form of the letters).
'and' anagrammed gives 'dan'.
'fan'+'dan'+'go'='FANDANGO'
'to' acts as a link.
(Other definitions for fandango that I've seen before include "Old Spanish dance, with castanets" , "Dance performed with castanets" , "Spanish Steps" , "Spanish courtship dance in triple time" , "Old Spanish dance in triple time" .)
