Composer caught at home holding dance (6)
I believe the answer is:
chopin
'composer' is the definition.
(Frederic Chopin)
'caught at home holding dance' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'holding' is an insertion indicator.
'dance' becomes 'hop' (hop is a kind of dance).
'c'+'in'='cin'
'cin' enclosing 'hop' is 'CHOPIN'.
(Other definitions for chopin that I've seen before include "Great Polish composer of phonic kind" , "Polish pianist-composer" , "No chip on this composer's shoulder" , "Frederic . . . . . ., great 19th century Polish composer" , "Polish virtuoso composer" .)
