Not at all sure why they called themselves the "Comedian" Harmonists. That vocal performance showed skill, talent, hard work, and respect for their material. Unless they were hamming it up for the camera while singing, there wasn't that much about it that I'd consider comic. It delighted me; my appreciation wasn't on a comic level, though.

Another thing I must point out: nowhere did you hear anyone inhaling, which is just superb. There are a lot of quality vocalists out there who could certainly take a lesson there.
