Oh haha I believe that was the group "Infinite Harmony" playing on the Live@WREK show. Thanks for listening! We have three a Capella groups on campus. Freshman year I attended one of the a Capella shows because my friend was a vocalist, and I was blown away by how much fun it was. They were really into the performance and did a great job of hamming it up. Van Canto probably would be just as fun live, but I could never see them becoming a favorite band or anything. It's like you said, I'd rather hear the real thing. However, it's really hard to dismiss the entertainment factor in play here!
