Composer ___ Vaughan Williams (5)
I believe the answer is:
ralph
'composer vaughan williams' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ralph that I've seen before include "Fellow's name" , "Man's name" , "Piggy's friend (Lord of the Flies); --- Vaughan Williams" , "Chap" , "man" .)
