The Mighty Boosh

Barratt stars as the character Howard Moon opposite Noel Fielding's Vince Noir in the comedy series The Mighty Boosh. Howard labels himself a "jazz maverick" and claims to be a multitalented intellectual, calling himself a "man of action", but he is actually unsuccessful in his literary and romantic ventures. He is unpopular with many of the characters, including Mrs. Gideon (who always forgets his name), Bob Fossil (who often uses Howard as a puppet for his bizarre schemes), and Bollo (who often says his name wrongly or ignores him completely). Barratt composed all of the music for the series, which includes a variety of genres such as rap, heavy metal, and psychedelic rock.
