Guitar Slim, Jr., was in street clothes the first time I saw him, just strolling on in to Jim Russel Records buy their last copy of his own album. Without recognizing him, you could tell by the way he dressed and the way he held himself that he was a performer. Sunday he was in full force, coming out howling "Everybody Knows About My Good Thing" in his ultra-showy outfit, giving every camera lens a personal smile.
