Well, I dont say you cant learn anything from Vaughan Williams arrangements,Peter paul and Mary, Waterson/Carthy. Fairport Convention, Kinston Trio, EII, Sean O'Riada, Ry Cooder,Nic Jones etc etc etc. Of course you can. But you may have a more profitable and fun journey if you go to the sorces of the music, the "pwoplw qho made the names we call it by" as well
