In 1992, Chambers formed his own band The Lemon Trees and wrote, produced and performed with them until they disbanded in 1995. The band only released one album - "Open Book". Following the end of The Lemon Trees, Chambers wrote with Cathy Dennis on "Am I the Kinda Girl?" and other albums before meeting Robbie Williams in January 1997. Their first work together, "Life thru a Lens", was released in September 1997. In the next five years, they produced four other albums: "I've Been Expecting You", "Sing When You're Winning", "Swing When You're Winning" and "Escapology". Following 2002's "Escapology", both Williams and Chambers went on to collaborate with other writers and artists for the next ten years, eventually reuniting for 2013's "Swings Both Ways", 2017's "The Heavy Entertainment Show" and 2019's "The Christmas Present".
