When I bit the bullet and admitted that most of the songs I wanted to sing were NOT Trad Unacc , a mate wrote out 'The Basic Run' in several keys - Major , relative minor , dominant and sub dominant , or C Am F G G7 etc , basic cjords of Paul Ankas' Dians and the main bit of Blue Moon . If you can play that run smoothgly in C , G , D , A , E , and F , you can fake MOST Folkie stuff !
