In addition, he has variously been a member of the Fabulous Thunderbirds and the Mannish Boys, plus supplied backing for Joe Bonamassa and Eros Ramazzotti.
He was the younger son of a Baptist minister, and gained enough confidence from watching his elder sibling, Walter, perform at their father's church, that Kirk learned to play rudimentary guitar by the age of eight.
Later through spending time with Al Blake, who was the lead singer and harmonica player for the Hollywood Fats Band, helped establish connections with other West Coast blues musicians such as Junior Watson and Lynwood Slim.
The opportunities that unfolded led Fletcher into a brief stint with Doyle Bramhall and a few guest appearances playing alongside Cyndi Lauper and Michelle Branch.
With his guitar playing producer Michael Landau, plus the horns of saxophonist Paulie Cerra and trumpeter Paul Litterall, Fletcher tackled Reed's "I Found Love," plus Stone's "Let Me Have It All".
The backing ensemble comprised Fletcher (rhythm guitar), Anton Fig (drums), Michael Rhodes (bass), Reese Wynans (piano, Hammond organ), Lee Thornburg (trumpet, horn arrangements), Paulie Cerra (saxophone), Nick Lane (trombone), and backing singers Mahalia Barnes, Jade MacRae, and Juanita Tippins.
