Uh-oh! I'm pretty sure now that that's not Darlene yodeling even though it's the segment I remembered--or misremembered. When I first viewed it, I thought her face looked different but decided it was because her hair was loose instead of in braids. I went back to the video today and clicked on the tiny triangle to see more information and noticed the name of a guest star, Roberta Shore. I googled her name and read that Roberta did the yodeling for the It's a Small World ride at the Disney parks! Now I wonder if I ever heard Darlene yodel.
