Singer in clubs given a wave (8)
I believe the answer is:
caroller
'singer' is the definition.
(I know that caroller is a type of singer)
'clubs given a wave' is the wordplay.
'clubs' becomes 'c' (abbreviation in card games).
'given' means one lot of letters go next to another.
'wave' becomes 'roller' (roller is a kind of wave).
'c'+'a'+'roller'='CAROLLER'
'in' is the link.
(Other definitions for caroller that I've seen before include "that makes Christmas music" , "Singer" .)
