Here's the full length of a BBC 4 documentary on Nile Rodgers, the guitarist who helped found Chic and then went on to produce all kinds of things, some of them huge top 40 hits. It's remarkable to see the lineup of interviewees in this doc, from collaborators like Bryan Ferry (there was definitely a mutual admiration society between them) to fans like Debbie Harry and Johnny Marr. The "hitmaker," incidentally, is the nickname of Rodgers' guitar.
There's plenty of tidbits for music fans, including confirmation (for me, anyway) that Le Freak had started off with a title that can't be said in polite company. (That will be your language advisory, too, by the way.)
