A 2009 book claims that the lyrics for The Sugar Hill Gang's seminal Rapper's Delight were plagiarized from the then-unpublished Caz's lyrics. In 2000, he set his account of the controversy in the song MC Delight. He claims in the song that he wrote the lyrics of Big Bank Hank, who had been the manager of his band, but never received any royalties or thanks for it.
