Are you kidding me? Listen I love Nate and have been following The Format and Fun. for years, but that was not a great performance by any means. Nate does miss notes and he missed notes in this performance.
The only reason he "missed a note" is because the sound guy didn't put the auto-tune on for the "some terrible nights..." part. Also the guy kept the vocoder effect on way too long. You can clearly see Nate get pissed when he runs off the stage, probably to say to the guy what the fuck? You can tell it's an incredible performance, just the mix in sound was all fucked. The sound on the drums was too low and you could barley hear Jack's guitar. All their voices were loud...if only the instruments sounded as loud it would've been amazing.
