a 2009 book claims that the lyrics for the sugar hill gang's seminal "rapper's delight" were plagiarized from the then-unpublished caz's lyrics.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 (henry jackson), who had been the manager of his band, but never received any royalties or thanks for it. jackson himself substantiated these claims as he neglected to change his verse on "rapper's delight" to reflect his own stage name, instead of beginning his verse with the now famous, "check it out, i'm the c-a-s-a, the n-o-v-a, and the rest is f-l-y." casanova fly is grandmaster caz's alternate moniker.
