Mississippi Macdonald last night. Very much blues in the style of BB King, and he did a couple of BBK numbers, along with Howlin' Wolf, Elmore James and Lightning Hopkins, but also a lot of his own stuff too. Good guitarist and a great blues voice too, the sort honed by a 40-a-day habit over about 50 years except I don't think he is 50 years old yet and I doubt that he smokes (no yellow fingers). Apparently he developed a love of the blues from growing up in the swamplands of Bromley.
