Aubrey tells Sway that he forgot about his bum knee in the City of Brotherly Love.

“What the footage doesn’t show is that I actually came out of the sky that night,” he told MTV News. “I was 20 feet in the air on a little platform. Philadelphia was the only sold-out show on the tour — 25,000 people. And before they see me, I see them for about five seconds. I was staring out into the crowd and I literally … when I landed on that platform, I blacked out and really forgot I was injured. I was just so full of adrenaline, so happy to be there, it kind of set in for me. I remember on the I Am Music tour, the reaction was great. But these were my songs. These are songs people know and love and we really made this happen in a short time. I was just enjoying myself. I had the mic and I was really going. And when ‘Best I Ever Had’ came on, I felt like dancing. It was a great moment. I wanted to run across stage, I wanted to jump into the crowd.”
