A few years ago I was sitting right in front of him at a music conference in NYC. It was during the day and indoors and he kept his sunglasses on the entire time. He was also walking around with a guitar for some reason. He never did play it. When a speaker saw him in the audience he pointed him out and because I was literally the person directly in front of him, I had hundreds of people looking and clapping at me (him), it was awkward to say the least.
