Medicine Head was a duo made up of guitarist John Fiddler who I think wrote the songs and Peter Hope-Evans who unusually played only mouth based instruments. They had a few hits in the early 1970s, mostly blues-based.

I couldn’t choose between them, so here are all four.

Medicine Head: One and One is One

Medicine Head: (And The) Pictures in the Sky

Medicine Head: Rising Sun

Medicine Head: Slip and Slide
