On June 30, it was announced on their official website that the girls had been invited to perform at the 2011 Special Olympics closing ceremonies in Athens, Greece. They performed the traditional Korean folk song "Arirang" along with "Nobody" sung in English and "Tell Me" sung in Korean. On August 5, The Wonder Girls appeared on Billboard.com's "Mashup Monday" program, performing a self-arranged cover version of B.o.B and Bruno Mars' "Nothin' on You". On October 9, 2011, a representative revealed, "The [English-language] album will be produced in a movie OST format. We'll be planning our concept to fit around the feel of the song, so as opposed to retro, we feel that it will be more pop. The Wonder Girls will definitely be coming out with a new image, so please look forward to it."
