Helped lead actor with screened recital (7)
I believe the answer is:
availed
'helped' is the definition.
(availing is a kind of helping)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for availed that I've seen before include "Helped" , "Used to one's advantage" , "Used, put into service" , "Profited from" .)
