Coldplay frontman Chris Martin was a guest on last night’s episode of Conan. In addition to performing an acoustic solo rendition of A Head Full Of Dreams track “Hymn For The Weekend,” he sat down and talked with the host for an interview segment. They covered a lot of ground, from Martin’s weird hometown to his opinions on Halloween to overzealous fans. They even sang a bit of “Yellow” in bad Cockney accents. Good times were had by all, I guess! Watch all the clips below.
