Search round for small dance band (5)
I believe the answer is:
combo
'small dance band' is the definition.
(I've seen this before)
'search round for' is the wordplay.
'search' becomes 'comb' (combing is a kind of searching).
'round' says to take the centre.
The middle of 'for' is 'o'.
'comb'+'o'='COMBO'
(Other definitions for combo that I've seen before include "Music group" , "group of players" , "musicians" , "Small (jazz or rock) band" , "Small jazz group" .)
