Play in Greek concert and cut number headed for America (10,5)
I believe the answer is:
prometheus bound
'play in greek concert' is the definition.
'prometheus bound' can be an answer for 'play' (I've seen this before). I am not certain of the 'in greek concert' bit.
'cut number headed for america' is the wordplay.
'cut number' becomes 'prome' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'headed' becomes 'bound' (I've seen this in another clue).
'for' means one lot of letters go next to another (I've seen this in other clues).
'america' becomes 'theus' (I've seen this in another clue).
'bound' put after 'theus' is 'theusbound'.
'prome'+'theusbound'='PROMETHEUS BOUND'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for prometheus bound that I've seen before include "Greek work" , "drama" , "play" .)
