Regularly-performed show wrongly viewed as rare show? (8)
I believe the answer is:
warhorse
'regularly-performed show wrongly viewed' is the definition.
I can't tell whether this definition defines the answer.
'rare show?' is the wordplay.
'rare show' anagrams to 'WARHORSE'.
But, I'm unsure how this is indicated.
'as' is the link.
Can you help me to learn more?
(Other definitions for warhorse that I've seen before include "Old soldier" , "something too often played" , "Copenhagen, say" , "Familiar piece of music" , "steed?" .)
