I was into Rhythm and Blues and not so much rock and roll. Also Fats Domino has been on a lot of lists...Several black singers made it over to popular music...But many good black singers songs were covered by white singers to make it acceptable to people...But when you mention Peggy Sue, I do remember hearing that at some time...There was a black radio station in Detroit that only played R & B. But its been so many years ago, my old brain cannot remember them all..
The other songs by B. HOlly that you mentions I never heard..
