OK, they sound pretty good, sort of like the old Ward Swingle "Swingle Singers", but I can't watch them without laughing about this scene from the old Woody Allen flick. You know the one.
VADoublegunner. It's been a long time since I've seen that Woody Allen flick! This group would be a whole lot more creepy if they were all wearing "Woody" masks and had tails!
Always was a fan of Bobby McFerrin as well. Very talented individual.
