Dolly Parton: 1 = 2
At the near end part of the video is the line from the lyrics saying "and the world will live as one," exactly while saying the word O.N.E., Dolly did the number T.W.O. sign.
See for yourself. My theory is that she's signaling "peace," more likely, however, the rest of the peeps before her frame, and the peeps on her background is gesturing one finger.
By the way, I liked her when she sang "The Day I Fall In Love," awwww how cheesy you ask? No, it's from the Original Sound Track of Beethoven's 2nd, the lovelife of a Saint Bernard. She sang it with James Ingram and it's sooo cute, maybe because of the line "Rollover Beethoven... won't you play with me?" Yay for Bestiality! Eww. Really...
