Over time Morgan would become a prolific songwriter for Hillsong. The next four Hillsong live albums (Touching Heaven Changing Earth, By Your Side, and You Are My World) featured songwriting contributions and acoustic guitars from Morgan, although he did not sing lead vocals on any of these recordings. His first official credit as a vocalist was on the album For This Cause. In Hillsong's 2002 live album, Blessed, the track "Most High" marked the first time Morgan contributed a lead vocal.
