On October 22 KST, MAMAMOO and B1A4 both appeared on the show to perform for everyone. To give everyone an amazing show, MAMAMOO brought out their hit songs medley which included "You're the Best", "Mr. Ambiguous", and "Decalcomanie". In addition to this, the group performed a J.Y. Park special highlight medley consisting of J.Y. Park's "Honey", "Swing Baby", "Elevator", and much more while even including the famous 'half-air-half-sound' quote.�

During the episode, MAMAMOO's Solar also covered Justin Timberlake's "Sexy Back" with her strong vocals and sexy dance that got the whole place hyped up but immediately became shy after performing the song. Along with this, Hwa Sa showed a completely different side as she beautifully sang Lee Moon Sae's "Whistle" and expressed how important the song it is to her and reminded of her family. As she started, everyone lost themselves in her voice, including B1A4's Sandeul.

While conversing with the groups, J.Y. Park praised MAMAMOO of their talents. He said, "It's my first time seeing them up close. It doesn't feel like I'm watching a girl group but rather 4 solo artists. Each member looks relaxed/comfortable and has different colors between one another. I think the phrase 'they look cool' fits them well."�

Check out all the performances.
