We were also at Ronnie Scott's when Chris Barber played. But I came into this popular music malarkey from jazz. In my youth, I saw many American jazz musicians (the Duke Ellington Orchestra, Woody Herman, Thelonious Monk, Dizzy Gillespie, Jimmy Smith, Roland Kirk and others, some of them more than once), plus lots and lots of British jazzers of the time (the Tubby Hayes Big Band in a place no bigger than Scott's was literally and metaphorically a real blast, the music entering your body and soul). From there to the classic blues and on to country blues and from there to folk and on to folk rock. It was a steady downward trend. And now I post on a Mark Knopfler forum - draw your own conclusions!
