Found vase for leading performer (4,4)
I believe the answer is:
star turn
'leading performer' is the definition.
'star turn' can be an answer for 'performer' (I have seen 'Top performer' mean 'star turn' so perhaps 'performer' could also mean 'star turn'). I'm not certain of the 'leading' bit.
'found vase' is the wordplay.
'found' becomes 'start' (as in to establish).
'vase' becomes 'urn' (both can mean a container).
'start'+'urn'='STAR-TURN'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for star turn that I've seen before include "Top item in entertainment" , "Leading act" , "Top of the bill" , "Headliner" , "Top act" .)
