The names that spring to mind are mostly golden oldies for me,James Taylor,Donovan,Neil Young on the blokes side,and Joni Mitchell,Judee Sill and the incomparable Dusty Springsteen for the ladies.After a lifetime in the music business I struggle a .bit with the newbies. It takes guts as well as talent to perform as a one-man show, and although not a big fan I admire Ed Sheeran on that score. One other who stands out spans a big time scale,Richard Thompson, he of Fairport Convention fame.One of the finest writers and guitar players this country has produced,even Hendrix was in awe of him,and having worked with him I can see why.
