Jay Z immediately jumped into a performance of "Public Service Announcement" after Cole put on a Roc-A-Fella chain and made the crowd throw up "tha roc" sign.

Unbeknowst to fans, Jay had a surprise for Cole before performing a second song, "F**WitMeYouKnowIGotIt." In honor of J. Cole's birthday, Jay told Cole to keep the chain he had one and that it was the very first chain he was given at Roc-A-Fella.
