the movie, he is shown as already being teamed up with producer Rick Rubin to form Def Jam, referred to as Krush Groove Records in the film. In reality, the label was started by Rubin in 1984 in his college dorm at New York University. Larry Smith was the producer of Run-D.M.C.'s first two albums, despite them being credited to Rick Rubin, who produced the group's third album, Raising Hell. Later on, the team was joined by its first popular teen sensation, LL Cool J, who plays a very small role in the movie at the age of 17. Playing himself, LL Cool J is discovered through his piece "I Can't Live without My Radio", which is performed at an audition in front of Dr. Jekyll and Mr Hyde, Jam Master Jay, DMC and Rubin in the latter's apartment. In reality, LL Cool J was discovered in Rubin's apartment but not through an audition. While going through a box of demos, Beastie Boy Ad-Rock stumbled across LL's demo tape. With this, he produced a beat and co-wrote "I Need a Beat" with LL and Rubin, which launched both of their careers, which allowed the Def Jam label to take off. The song "I Can't Live without My Radio" was made for the movie as a way for LL Cool J to star in it. However, this song was also one of the hit songs on his debut album Radio. The Fat Boys were the first group to showcase a human beat box while rhyming. In the movie, the group originally referred to itself as the Disco Three. It was not until a scene in an Italian buffet, where the three boys took the phrase all you can eat to the next level by eating everything. When the group realized that they were really fat, they decided to give themselves the name Fat Boys. In reality, the name Fat Boys was suggested by the group's manager when he received a $350 hotel bill for extra breakfast ordered by the group on their European tour. As portrayed in the movie, the group was discovered through the Coca-Cola and Tin Pan Apple hip-hop contest at Radio City Music Hall, where the trio won the grand prize—a recording contract—but had entered the contest to win the second-place prize, a stereo set. The group perform their songs "Don't You Dog Me", "All You Can Eat",
