Singer ____ Clapton (4)
I believe the answer is:
eric
'singer 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 "-- Idle, comedian" , "Great Norwegian explorer .... the Red" , "..... the Red was Norwegian 10th Century exployer" , "Fine" , ".... the Red, Norwegian explorer who discovered Greenland in 10th century" .)
