Musician ____ Clapton (4)
I believe the answer is:
eric
'musician clapton' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eric that I've seen before include "Mr Clapton" , "- Morecambe, comic" , "Boy's name" , "---- Roberts, actor brother of Julia" , "Rice turned for the boy" .)
