Using a wide array of archive and some fairly honest and potent interviews, this documentary presents us with a short biopic of rather an enigmatic gent. Initially, his dulcet tones earned him a decent enough living doing lucrative commercials and providing backing vocals until a session with David Bowie started his career on a largely unhindered upwards trajectory. His associations with Aretha Franklin, Bette Midler and Roberta Flack, his total - almost perfectionist - commitment to his art and his cheeky sense of humour all contributed further to a success that transcended not just US racial boundaries, but also physical international ones too. I wasn't really that aware of his music, but watching this does effectively illustrate just how many songs he was behind - writing and/or performing, that are more familiar than I'd expected. This also wasn't a messy man. He wasn't in and out of the papers with stories of his life, his lifestyle, his drinking or drug taking - he actually comes across as a remarkably stable man in many ways, even if his solution to problems he faced was to reach for the fried chicken bucket or the ice cream spoon. Happily, we don't really focus too much on the personal life. Perhaps because his own comments of "mind your own business" are echoed by the film's contributors who knew him and who chose not to add fuel to any fires burning about his sexuality. It's a celebration of his music that broadens awareness for folk like me who didn't realise the scope of his skills, and it is a fitting and spangly tribute for those who did.
