Shall listen to the number when I can do so properly – plugging in ear-bud thingeys etc. Hear what you say about the blues; not everyone’s cup of Earl Grey. But is is/was instrumental in the formation of rock, pop, soul – virtually all modern stuff. I find it fun to hear the origins of so much material. Moreover, as a axe-lady in waiting, I think you might find some of the guitar work on the Baldry album really interesting.
