The “Right Here Waiting” hit-maker opens up about the 14 number ones he’s penned and the grateful life he leads. He takes it back to his early days when Lionel Richie called Marx’s family home (!) to encourage him to make the move to LA, and Kenny Rogers bought his song when Marx was still a young backing singer. He also explains how Barbra Streisand passing on one of his songs proved to be the biggest break of his career, and why Twitter proved to be an unlikely meeting place for him and his now-wife, Daisy Fuentes.
