He composed butchers' dance (8)
I believe the answer is:
schubert
'he composed' is the definition.
The definition suggests a singular noun which matches the answer.
'butchers' dance' is the wordplay.
'dance' is an anagram indicator.
'butchers' with letters rearranged gives 'SCHUBERT'.
Can you help me to learn more?
(Other definitions for schubert that I've seen before include "Composer of song-cycle Winterreise" , "Austrian composer and prolific songwriter" , "Famous man behind bars" , "Franz --, Viennese composer" , "Lieder composer" .)
