Elaborate spectacle (7)
I believe the answer is:
pageant
'elaborate spectacle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pageant that I've seen before include "Elaborate procession on historical theme" , "Tableaux or dramatic scenes depicting historical events" , "Rich parade" , "Spectacular ceremony" , "Magnificent parade" .)
