After bringing the roof down and winning the song festival on Infinity Challenge last week as Future Liger with Let's Dance, MC Yoo with married couple, Yoon Mi Rae (Tasha) and Tiger JK reunited on MBC Music Core a week later to excite fans once more with another live performance. This was made possible because the song festival's grand prize entitled them to perform once on Music Core. Tiger JK expressed, "Yoo Jae Suk was really nervous about performing on Music Core and called Yoon Mi Rae a few days before, expressing his anxiety. He even told her that it would be ideal if they had pre-recorded their performance. To allay his nervousness, we came together on 17th July for an additional rehearsal." Tiger JK added, "Hyung (Yoo Jae Suk) is really an angel. I tried really hard to find out his weak points but didn't manage to do it. It was really enjoyable working together with Yoo Jae Suk." credit: CodeMonMonSeason2 Their first performance on Infinity Challenge. credit: smint134
