Audio problem: When Buckwheat says, "It's worse than I thought", while watching Alfalfa and Darla in the boat, you can see Uh-Huh next to him mouthing that line.
Audio problem: At the talent show, where Waldo does his duet with Darla, you can tell he's lip synching. Sometimes he mouthes the words too late or too early. And in shots where he has his head up, his Adam's apple isn't moving, a sure sign no noise is coming out of him.
Suggested correction: It is likely he was not singing live, but the reasoning for saying it is obvious doesn't quite work considering two details. The first being that Blake Ewing was Broadway and choir trained for singing where he was taught to sing "big" so to say which involves a large amount of mouth movement making it look like he's singing when he's not. This can be seen in other footage of him singing as a child. He is also a kid so his Adams apple is tough to make out movement wise. Especially with his collar.
Audio problem: When Darla and Alfalfa are in the boat, Darla says "Oh Alfalfa, you're a sweety poo" or something, but when she says "sweety poo", her lips don't move.
