Anyone with two eyes can look it up and see that Berry's first hits came out in '56. Bill Haley and the Comets first hits came out in the early '50s. Clearly Haley invented Rock & Roll.
Additionally, 'Rock Around The Clock' still gets lots of radio time to this day.
Hail to Berry? He did not invent Rock & Roll. Also, he was pretty much a slimebag. He was imprisoned three different times, for statutory rape, armed robbery and sexual assault. He also videotaped women getting dressed in one of his clubs. He was later found with videos of these naked women in his home after a raid. These offences happened throughout his life, young, middle aged and old.
