2AM recently released footage of a surprise a capella performance in a subway station on their me2day site. The event occurred on November 3rd (KST) in the afternoon on subway line 2 and is reported to have gathered quite a crowd despite not being announced beforehand. They performed their new single "Like Crazy" in a capella style. Jo Kwon stated, "We prepared this because we wanted a lot of people to hear our song. It seemed like a good idea to perform in the subway for a bit, and ironically, a lot of people showed up, so we were worried that we became an interference." Source + Photo: Newsen
