Whether you know it or not, you've been listening to Fonzi Thornton for almost 50 years. As teenagers he and Luther Vandross formed a lifelong friendship and devoting their lives to music pays off for both - Luther becomes a giant among giants and Fonzi becomes one of the most sought after backup singers ever. Starting in Listen My Brother with Luther and friends Carlos Alomar and Robin Clark turns into a stint singing with Chic and then a lifelong partnership with Roxy Music and Bryan Ferry. Along the way there's been Bowie, Aretha, Scritti Politti, Candi Staton and tons more. Don't forget to watch him in the excellent new documentary Luther: Never Too Much that will be premiering on CNN on New Year's Day. Enjoy!
