I agree with you Matthew, the bands Letterman performance was a notch above this one, and yes Letterman's sound engineers need to give Coco's a few pointers. Cat's bass playing needs to be heard, she's not just there cause she is good to look at! Go back and listen to the Letterman performance, the fact that Cat's bass was actually given some respect made it a top flight solid home run. I also have to add that Grace seemed tired on Conan and her voice showed it. Has she taken a break yet?
