Apple employees all had a big party at Apple Park Friday night, celebrating the completion of the campus, and there is a surprise guest.

Lady ga ga took the point at 8 p.m., and NBC Bay Area includes a few drone aerials of this audience waiting for her which was just about the extent of a normal concert. The point, which had been set up at in the mountainous area in the middle of the spaceship doughnut, had rainbow arches on it, harkening back to Apple logo.

Employees just found out that ga ga could be performing at the case, which had been a party of finally getting everyone else designed by architect Norman Foster transferred in to the circular campus and completed at 2017-2018.

The main building is 1000 meters in diameter, and it has a circumference of the complete mile. It’s a ring entirely in glass, and was the vision of the stevejobs, whom CEO Tim Cook gave tribute to on Twitter Friday.

But somewhere through the concert, even ga ga could have felt like some of this audience wasn’t with her, or some thing, and she took out a moment to say”Even though I had been asked to play to tonight… plus a number of you could well not like me but thanks for coming… But if you don’t like this, and you are here, of course if you believe you’ve got any shit that you may say to hurt me bring me back down or make me feel a while I have never felt previously, then you are fucking wrong.”

Anyway, here is some more societal media evidence, for example from a few obvious fans of ga ga among the Apple work force who raced to find rankings before this point.
