Musical based on Dickens (6)
I believe the answer is:
oliver
'musical based on dickens' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oliver that I've seen before include "First name of Dickens boy Twist" , "Cromwell, for example" , "Dickens boys who asked for more" , "Hardy, maybe" , "* [DICKENS WORK] Untwisted" .)
