I believe the answer is:
cats
'andrew lloyd webber musical' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cats that I've seen before include "Spectacular Llyod Webber feline musical" , "Musical; jazz fans" , "Musical from TS Eliot" , "Domestic pets" , "Musical; animals" .)
