Heavenly performers? (5)
I believe the answer is:
stars
'performers?' is the definition.
(star is a kind of performer)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for stars that I've seen before include "Leading actors" , "''What is the ...? What is the ...? '' (Juno and the Paycock)" , "Heavenly bodies" , "Leading performers (with stripes?)" , "Horoscope (colloq.)" .)
