dance

I'm a little stuck... Click here to teach me more about this clue!

'charleston?' is the definition.
(charleston is a kind of dance)

I can't explain the remainder of the clue.

(Other definitions for dance that I've seen before include "Jig, caper" , "Fling" , "Perhaps reel" , "Steps" , "Eg, perform ballet" .)

I've seen this clue in The Sun.
