We’ve kept you updated regarding Brian Wilson’s That Lucky Old Sun and connected live appearances. It’s not very original of me to say witnessing Wilson 2008 can be painful — for some reason, his performance on Conan last night struck me as especially rough. Maybe because he seems happy, but also generally confused. He never uses his keyboard. He just sorta raises his hands, feels the music. When Conan thanks him he seems confused. He looked more on top of things in the Black Cab, so maybe just an off day? Brian is clearly no longer one of the greatest singers of all time, which is sadly apparent following his performance of “Forever She’ll Be My Surfer Girl” when he and his Wondermints dig into “California Girls.” You can watch it at Hulu.
