Jonathan Cain

Cain was born in Chicago to Leonard and Nancy Friga. At the age of eight, Cain began accordion lessons, and by the time he was in his teens, he was playing accordion and piano at parties and in clubs. He also plays guitar, bass, and harmonica. Cain is a survivor of the Our Lady of the Angels School fire of 1958, which took the lives of 92 students and three nuns. In 1968, Cain graduated from East Leyden High School in Franklin Park, Illinois, a Chicago suburb, and later attended the Chicago Conservatory of Music.

Cain has been married three times. His first wife was actress and singer Tané McClure, for whom he wrote the 1983 hit song "Faithfully". In 1989, he married his second wife, Elizabeth Yvette Fullerton, with whom he has three children: Madison (1993) and twins Liza and Weston (1996). He and Elizabeth divorced at the end of 2014. Madison is married to Trev Lukather, Steve Lukather's son. In April 2015, he married minister Paula White, making it the third marriage for both. They reside in Apopka, Florida. Jonathan has two younger brothers, Thomas and Harold. Cain and David Kalmusky designed and built Addiction Sound, a recording studio in Nashville, Tennessee. Cain is a devout Christian and believes this is reflected in his work creating and sharing Christian music. In November 2022, Cain performed "Don't Stop Believin'", which he co-wrote, at a party at Donald Trump's Mar-a-Lago estate. Journey bandmate Neal Schon's attorney sent Cain a letter accusing him of damaging the "Journey brand" by performing at a political event, and asking him to refrain from representing Journey at such events.
