Audio problem: At the beginning, when RUN DMC is recording "King of Rock," they are highly animated with their body movements. The mic is not accurately positioned to keep the vocals consistent. (00:01:04 - 00:02:10)
Audio problem: During the live performance of Kurtis Blow, on the hook, the girls singing backup have the mics in front of their mouths. His vocals would have faded away when they moved the mic. (00:33:18)
