On March 22, Crayon Pop held a comeback guerilla showcase at Myeongdong, COEX, and Hongdae. 

Crayon Pop performed their famous "Dancing Queen" and "Bar Bar Bar" to get the crowd excited.  

At the end of the showcase, Crayon Pop performed their new song, "FM," which has yet to be released.  

It has been reported by OSEN that so many people attended that the venues were "paralyzed" by traffic.

On March 21, their first showcase was held at the Doota Plaza at Dongdaemoon, where they performed "FM" for the first time.

"FM," which was produced by Shinsadong Tiger and Monster Factory, will be released on March 27.
