Co-operate with entertainment on stage and dance (4,4)
I believe the answer is:
play ball
'co-operate' is the definition.
(I've seen this before)
'entertainment on stage and dance' is the wordplay.
I cannot really see how this works, but
'entertainment' could be 'play' (I've seen this in another clue) and 'play' is found in the answer.
'dance' could be 'ball' (ball is a kind of dance) and 'ball' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'with' is the link.
Can you help me to learn more?
(Other definitions for play ball that I've seen before include "go along" , "Most boys love to" , "Be cooperative" , "Agree to comply with someone else's rules" , "perform service in court" .)
