During the English Folk Revival of the 1960s, Faulkner met and developed a professional relationship with singer/songwriter/folklorist Ewan McColl and his wife Peggy Seeger, who in turn introduced Faulkner to the world of British and Irish folk music.
When Faulkner was living in Britain in the late 60s and early 70s, he became close and began to play with many of the best London-based traditional Irish musicians, including West Clare fiddler Bobby Casey, piper Tom McCarthy, and Sligo flautist Rodger Sherlock.
In the 70s, Faulkner wrote the music for the BBC children's television show "Bagpuss." Then, in 1977, he met and married Co. Galway singer and De Dannan founder Dolores Keane. The couple worked on several more film scores for the BBC as well as formed the successful Trad bands "The Reel Union" and "Kinvara," recorded three duet albums, toured extensively throughout the US, Canada, Australia, and Europe, and collaborated on several musical projects.
