In 1984, Little Richard filed a $112 million lawsuit against Specialty Records; Art Rupe and his publishing company, Venice Music; and ATV Music for not paying royalties to him after he left the label in 1959. The suit was settled out of court in 1986. According to some reports, Michael Jackson gave Little Richard monetary compensation from his work when he co-owned (with Sony-ATV) songs by the Beatles and Little Richard. In 1985, Charles White released Little Richard's authorized biography, Quasar of Rock: The Life and Times of Little Richard, which returned Little Richard to the spotlight. Little Richard returned to show business in what Rolling Stone would refer to as a "formidable comeback" following the book's release.  Reconciling his roles as evangelist and rock and roll musician for the first time, Little Richard stated that the genre could be used for good or evil. After accepting a role in the film Down and Out in Beverly Hills, Little Richard and Billy Preston penned the faith-based rock and roll song "Great Gosh A'Mighty" for its soundtrack. Little Richard won critical acclaim for his film role, and the song found success on the American and British charts. The hit led to the release of the album Lifetime Friend (1986) on Warner Bros. Records, with songs deemed "messages in rhythm", including a gospel rap track. In addition to a version of "Great Gosh A'Mighty", cut in England, the album featured two singles that charted in the UK, "Somebody's Comin'" and "Operator". Little Richard spent much of the rest of the decade as a guest on TV shows and appearing in films, winning new fans with what was referred to as his "unique comedic timing". In 1989, Little Richard provided rhythmic preaching and background vocals on the extended live version of the U2-B.B. King hit "When Love Comes to Town". That same year, Little Richard returned to singing his classic hits following a performance of "Lucille" at an AIDS benefit concert.  In 1990, Little Richard contributed a spoken-word rap on Living Colour's hit song, "Elvis Is Dead", from their album Time's Up. The following year, he was one of the featured performers on the hit single and video "Voices That Care" that was produced to help boost the morale of U.S. troops involved in Operation Desert Storm. He also recorded a rock and roll version of "The Itsy Bitsy Spider" that year that led to a deal with Disney Records, resulting in the release of a hit 1992 children's album, Shake It All About. Throughout the 1990s, Little Richard performed around the world and appeared on TV, film, and tracks with other artists, including Jon Bon Jovi, Elton John and Solomon Burke. In 1992 he released his final album, Little Richard Meets Masayoshi Takanaka featuring members of Richard's then current touring band.
