Last night Brian Wilson performed on The Tonight Show in support of his latest release "That Lucky Old Sun." I have much respect for Wilson and have been an avid Beach Boys fan during certain times in my life, but who was that? He sat in front of a keyboard that he never played, and during parts of the song he simply stopped singing. His voice was rough and contrasted greatly with what I hear on the album. Has he always performed like this, or is this a recent development?
