Beat a touch upset in dance (7)
I believe the answer is:
lambada
'dance' is the definition.
(I've seen this before)
'beat a touch upset' is the wordplay.
'beat' becomes 'lam' (I've seen this before**).
'touch' becomes 'dab' (dab is a kind of touch).
'upset' says the letters should be written backwards.
'a'+'dab'='adab'
'adab' backwards is 'bada'.
'lam'+'bada'='LAMBADA'
'in' is the link.
(Other definitions for lambada that I've seen before include "Lively Brazilian dance" , "few steps?" , "Erotic Brazilian dance" , "Fast Brazilian 3 dn" , "Fast Brazilian dance - mad Baal (anag)" .)
