Paul McCartney headlining Apple’s 50th anniversary bash at Apple Park tonight

Paul McCartney is officially set to perform at Apple Park in celebration of Apple’s 50th anniversary. The legendary artist was spotted sound checking yesterday evening at Apple’s headquarters ahead of the gig set to take place later tonight …

In a post on Reddit, a user shared an image of McCartney’s soundcheck last night, seen above.

You can see the former Beatle and the rest of his band on the rainbow stage inside the Apple Park ring. The rainbow structure has been transformed into a proper concert setup with stage lights and all. There are large screens on either side of the stage so people dispersed throughout have a great view.

Apple employees were reportedly not given a plus-one for the McCartney show, so it sounds like it will be limited solely to Apple workers themselves.

The concert is set to take place tonight, ahead of Apple’s formal 50th anniversary tomorrow, April 1. It caps off several weeks of celebrations from Apple, including performances by Alicia Keys at Apple Grand Central in New York City and Mumford & Sons at Apple Battersea in London.

There’s no word on whether Apple plans to record the Paul McCartney show and release it to the general public.
