The November 12 airing of MBC's 'Idol Radio' had a special guest panel - the "students" of 'Idol Radio High School'!

Alongside DJ BTOB's Ilhoon, current high schooler idols ASTRO's Sanha, Stray Kids's Seungmin, Lee Eui Woong, and Yu Seon Ho made up a brand new team called the "Crumblies", threatening 'Idol Radio's resident special team the "Rose Field Boys". 

On this broadcast, the 4 high school idols discussed what they've been up to lately, the upcoming CSATs (which Sanha revealed he was not taking), as well as sending out open-hearted messages to their close hyungs. 

Yu Seon Ho and Lee Eui Woong then had a throwback to the old days and performed "Pick Me" from 'Produce 101' season 2 together, followed by a medley of songs like "Sorry, Sorry", "Ko Ko Bop", "Fire", "Likey", and more. Likewise, Stray Kids's Seungmin and ASTRO's Sanha had a medley dance time of their own with Seungmin performing various JYPE sunbae group tracks as well as "DNA" plus Sanha performing "Dope" and "Bang Bang Bang".
