Go up to organise dances (6)
I believe the answer is:
ascend
'go up' is the definition.
(I know that ascend is a type of go up)
'organise dances' is the wordplay.
'organise' indicates anagramming the letters.
'dances' anagrammed gives 'ASCEND'.
'to' is the link.
(Other definitions for ascend that I've seen before include "Dances (anag.)" , "shift to a higher plane" , "Take off" , "Travel upwards" , "Move upwards" .)
