This image provided by the estate of Dick Waterman, shows Arthur Crudup, center, with Fred McDowell, left, and Robert Pete Williams. Crudup wrote the song “That’s All Right,” which Elvis Presley later recorded for his first single. But Crudup received scant songwriting royalties because a record contract funneled the money to his original manager. Crudup died in 1974, leaving behind one of the starker accounts of Black-artist exploitation in the 20th Century. (Dick Waterman via AP)
