Musical based on Eliot poems (4)
I believe the answer is:
cats
'musical based on eliot poems' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cats that I've seen before include "Musical (felines?)" , "Musical; animals" , "Popular musical" , "Pets - musical" , "Siamese, Persian etc" .)
