The 15& girls had announced their guerrilla concert just the other day, but they attracted tons of fans anyway even with the short notice!

Park Ji Min and�Baek Ye Rin held 4 different guerrilla concerts on April 8th. They started at the girls' high school at 12:30 PM, moved onto the Seogang University at 3PM, then Sejong University at 5:30 PM, and finally onto the Gangnam Station M-Stage at 8PM.� The girls even live-streamed the Gangnam Station concert for those fans unable to make it.

J.Y. Park himself helped the girls out for the event, where they performed "Somebody", "I Dream", and covered "Be My Baby", "If I Ain't Got You", "Girlfriend", and "Irreplaceable".

Check out some of the performances below!
