I never knew Tony Blackburn, Terry Wogan or Cliff wore a wig
I assumed Cliff just died his hair
Others are famous for it , Brucie, Elton, Paul Daniels etc
Except for Ernie Wise who was famous for the wig that actually wasn't
It's so obvious that Cliff Richard wears a wig. In photos that have been taken above him, you can clearly see a line where his wig sticks to his head or pins to his hair.
