co-written "Only One Love in My Life". In 1981, The Pointer Sisters peaked at number two for three weeks on the Billboard Hot 100 as well as number 7 on the R&B chart with "Slow Hand", written by John Bettis and Michael Clark, with Conway Twitty making it a number one hit on the Billboard Hot Country Singles chart the following year. Clark and Bettis also co-wrote Juice Newton's "Heart of the Night" and Donna Summer's "The Woman in Me". In 1983, Bettis gained his biggest achievement with "Human Nature", a ballad penned for Michael Jackson's multi-platinum album Thriller. Originally a throwaway lyric and melody snippet composed by Toto's Steve Porcaro, the entire song was later written in its entirety by Bettis and Porcaro in two days. Thriller became the best selling record of all time, and "Human Nature" has since been recorded by Boyz II Men, Miles Davis, John Mayer, George Howard, Christine Collister, and David Benoit. It has also been sampled by SWV, Ne-Yo, 2Pac, Lil Wayne, Nas, Jason Nevins and Chris Brown. In the same year, Barbara Mandrell's "One of a Kind Pair of Fools" reached number one on the country chart. In 1985, Bettis accepted an assignment in Hollywood to write a song for the soundtrack of the film Vision Quest. The end result was "Crazy for You", a song not originally written for, but recorded by Madonna, who also performs it in the movie. The song was an international hit, and led to the film being re-titled Crazy for You when it was released in the UK and Australia. Perhaps Bettis' best-known commissioned work is "As Long as We Got Each Other", co-written with long-time collaborator Steve Dorff as the theme song to the hit ABC Network television sitcom Growing Pains, sung by five-time Grammy winner B. J. Thomas for six seasons, solo for season 1; and, as a duet with Jennifer Warnes for seasons 2, 3, 5, and 7; and with Dusty Springfield for season 4. In 1988, he co-wrote "One Moment in Time" with Albert Hammond which was recorded by Whitney Houston as the theme for the Summer Olympics. John Bettis continued developing an eclectic catalog into the 1990s. 1991's "Can You Stop the Rain" topped the R&B charts in 1991 for Peabo Bryson. "If You Go Away" was a top 20 hit in 1992 for New Kids on the Block, and "Heartland",
