A Different World The theme song was co-written by Stu Gardner, Bill Cosby, and Dawnn Lewis â€“ who was also a cast member. In the online interviews related to the 2006 "Hillman College Reunion," Lewis revealed that her being approached to write the song and to audition were two separate events that occurred within a short time of each other, such that she thought it was a practical joke by her friends. The song was performed by Phoebe Snow in season one, then by Aretha Franklin in seasons two through five, and Boyz II Men in season six.
