You bring up My Fair Lady once and look what happens. In a blast from Chris Martin’s past, Conan O’Brien decided to make the Coldplay front man take a walk down memory lane to a time when he wasn’t in one of the biggest bands in the world, but just a wee lad with dreams of being a musical-theater star who once played Eliza Doolittle’s dad. And you know what that means: cockney accents galore. Rather than bust out one of the show’s classics, the two chimney sweeps in another life pulled out some hats, scrunched up their shoulders, and got to singing “Yellow†in full-blown butchered cockney. (For being from Massachusetts, Conan is really the surprise winner at this.) Conan and Chris’s Cockney Classics coming down a chimney near yaaaa this Christmas.
