If you believe Conan O'Brien, Jens Mueller is a virtuoso musician, responsible for the breezy piano music that accompanies Apple's commercials and product launches. The supposed Apple employee made a chuckleworthy appearance on Conan's show last night, playing the latest in a line of suspiciously similar product launch jingles to celebrate the iPhone 6's announcement. Last night's show had another Apple appearance — Conan's guests also included John Hodgman, the comedian who spent four years playing a PC in Apple's famous "Get a Mac" ads.
