Curtis Brown (born April 18, 1960), better known by the stage name Grandmaster Caz or Casanova Fly, is an American rapper, songwriter, and DJ. He was a member of the hip hop group The Cold Crush Brothers from 1979 to the mid-1980s. He is best known as the (uncredited) main writer of Big Bank Hank's raps on the seminal 1979 hip hop single by The Sugarhill Gang, "Rapper's Delight". He worked with Debra Harris as a celebrity tour guide for Hush Hip Hop Tours, a hip-hop cultural sightseeing tour company in New York City, and is a board member of The Kennedy Center's Hip-Hop Council, Hip-Hop Ambassador and board member for Windows of HipHop and CEO of GMC Entertainment Inc. Musical career Caz first encountered rap in 1974 at a Kool Herc block party. Shortly after, he teamed with DJ Disco Wiz under the name Casanova Fly to form one of the first DJ crews, Mighty Force.

Caz admits that he himself stole new equipment during the New York City blackout of 1977. In 2015, Caz was featured on the single "Downtown" by Macklemore and Ryan Lewis.

Jackson had never rapped before, and asked Caz for lyrics to use. This is most evident in his opening verse, when, instead of introducing himself as Big Bank Hank, he raps, "Check it out, I'm the C-A-S-A-, N-O-V-A, and the rest is F-L-Y". (Casanova Fly is Grandmaster Caz's alternate moniker.) Big Bank Hank's verse in the song about seducing Lois Lane away from Superman was also lifted from Caz. In 2000, Caz released the song "MC Delight", a parody of "Rapper's Delight" which told his side of the story. In the song, Caz states about giving away his lyrics, "I
