The day he is referencing was one of the angriest days of Jobs late tenure at Apple.
Jobs was furious, indignant, and as angry as he could be that a flaw was found in his precious iPhone.
Jobs was baring his teeth during the entire event while countering with "we LOVE our customers". It was a really sad and poorly thought out affair.
Job was not dancing to this guys song. He was trying to pretend to contain his absolute rage. I was there. Watch the video. Jobs was incensed not happy and that video was a prop.
And I lived just a few miles from cupertino at the time, and believe me every call I made was dropped due to that spot on the antenna.
