Craig Charles profiles producer/songwriter/singer and funk guru George Clinton, whose overlapping enterprises Parliament (formerly doo-wop quintet the Parliaments) and Funkadelic have influenced top R&B and hip-hop acts with their radical packages of drug-fuelled music, singular fashions and over-the-top onstage theatrics. The Clinton canon includes Tear the Roof off the Sucker (Give up the Funk) and One Nation under a Groove Part I.
