I recognized Norman almost immediately, when I spotted him on the ferry, having done my homework about who was going to be performing at the event. Also, with he and I being the only two people on the boat of obvious African descent, and my not being the one wearing the trademark hat, one would have had to be blind not to notice him! ;)
I spoke with him briefly after I took the shots and discovered that he had just flown in from London and was very tired as a result of the long flight. He explained to me he was keeping the sunglasses on to hide his tiredness.
