In 1990, King and Bo Diddley, along with Doug Lazy, recorded a revamped hip hop version of the Monotones' 1958 hit song "Book of Love" for the soundtrack of the movie "Book of Love". He also recorded a children's album, "I Have Songs In My Pocket", written and produced by children's music artist Bobby Susser in 1998, which won the Early Childhood News Directors' Choice Award and Dr. Toy's/the Institute for Childhood Resources Award. King performed "Stand by Me" on the "Late Show with David Letterman" in 2007. Ahmet Ertegun said, "King is one of the greatest singers in the history of rock and roll and rhythm and blues."
