ジャニーズWEST 8th single "Bokura kyou mo Ikiteru / Kangaeruna Moero!" Color-coded Lyrics

Hi! I putted colors to the lyrics to determine who sang each part of the song. Below are the color of the members. Anyways, regarding with the color code of SHE IS MY... I am still 80% sure of the colors. I am having a hard time to determine who sang the "She's my Baby!" echo in the song. Their voices were too much edited. So if I have mistakes please do comment ~
