Today, the girls showed up on Maybee's Volume Up Radio on KBS Cool FM. It's the first radio show they did since Amber, Krystal and Sulli got hit by the swine flu. Now, it's good to hear that they are fully recovered and back on the playing field. During the program, IU called in and it turns out the girls are very close to IU. The girls were even seen singing "marshmallow, marshmallow" very cutely. Be sure to check out the videos of F(x) performing Chu~ live as well as Luna's solo cover of Navi's song "On the Road". Plus, the girls did a very short cover of SNSD's "Gee" which is a must see! So, go watch the videos, now!
