"Royalty" was all over the stage at Hill Auditorium Oct. 19-first there was Radio King and His Court of Rhythm, then a visitor who might be described as the uncrowned king of the last Blues and Jazz Festival, and finally, the king of them all, B.B. King, the King of the Blues. And what the audience lacked in size, they made up for in enthusiasm, in a show that went on till almost the midnight hour. In fact, the only mar to an otherwise fine evening was some trouble in the sound system, which, fortunately, was cleared up shortly after B.B. took the stage. It did detract a little from Radio King, a fine local group, who do a revue-type act, and very well, too. They've been playing the Ann Arbor clubs (and a few larger out-of-towif clubs), and are an exciting bunch to watch and listen to. For this date they were joined by the Soulful Soulmates, a quartet of young dudes whose voices match their ñames. But the star of the act is a young lady named Lois Scott whose voice can bowl you over one minute and wrap you around her finger the next. The guest "royalty" was the hit of the last festival, One-String Sam, from Detroit, who drew a standing ovation after two numbers, and got another for his encoré. As for B.B., well, he's still the King. Part of his band missed the plane from Sacramento, so he only had a piano, bass, drums, and baritone sax backing him up, but it didn't matter much. His gestures seem a bit more rehearsed, his guitar "Lucille" has changed color (from red to brown), but sounds the same (maybe even a bit more mellow), his timing and his voice are still a thing of joy, and the dynamics of his instrumentals are a master lesson in how to play blues guitar. Fortunately (maybe because most of his horns were not there), he eschewed the popsoul sound he took up on his latest album, and played mostly the blues. And when the good Dr. King gives a lesson on the blues, as he did in "Blues In The Morning" or "Cryin' Won't Help," all students get gradúate credit.
