When you're monitoring the VIP guests getting into a Grammy Awards After-Party, it may be good to know "who's who". In this case, the worst decision of your life.

Sure, there's only so much room for VIP guests when you throw a Grammy Award After-Party, but denying Sir Paul McCartney, Beck, and Taylor Hawkins from getting into the door to the party? This may be grounds for getting your ass kicked by every rocker in the world!

TMZ caught video footage of the 3 rock legends being denied access to Tyga's after-party event at Argyle in Hollywood. After McCartney was denied the 2nd time, he asked "How VIP do we gotta get?". Obviously an epic sign of the times we live in now...
