So, I was telling one of my best friends about Johnny's Jrs. and some of the groups. And I brought up how MatsuJun, Aiba, and Nino all were in a group together "with this other guy named Ikuta Toma". & she said she wanted to hear them, but I told her I could never find a song by M.A.I.N when I searched. So we looked around again and STILL NOTHING. But for the group to be formed, they had to sing something, right?? Well, where would that something be? Does anybody know? Please help me out, the curiosity is killing me. =P
