Stephen Anthony James Duffy (born 30 May 1960, in Birmingham) is an English songwriter, vocalist, and multi-instrumentalist. He has recorded as a solo performer under several different names, and is the lead singer for the group, The Lilac Time. He has also co-written many songs with Robbie Williams, and Steven Page of Barenaked Ladies.
Duffy's songwriting ability earned him his first Number 1 in October 2004, as the co-writer of the Robbie Williams single "Radio," one of two new tracks recorded for Williams' Greatest Hits album.
In October 2005, Robbie Williams released the album Intensive Care, fully co-written and co-produced by Stephen Duffy. It gained him a great deal of exposure, critical acclaim and 7 million sales worldwide. Duffy went on to work as the musical director and guitarist for the Robbie Williams Close Encounters world tour.
In 1987 Duffy was contacted by Steven Page, then of the band Scary Movie Breakfast, and was impressed by his writing and demo tape. Duffy and Page began co-writing songs. Their work together produced popular Barenaked Ladies songs like "Jane", "Alcohol" and "Call and Answer" as well as material on Page's solo album "The Vanity Project".
