if someone who likes and understands folk music is teaching diction they are not going to destroy accent for the sake of diction.
jim still has given no evidence or stats to back up his "often" statement.
neither has it anything to do with amateur or professional, it has more to do with an understanding of the genreand familarity with folk traditional music.
canal wheeler,I find your posts utterly tedious too, all this drivel about some performer who according to you only sings 3 songs ,but performs them well, and this stuff about someone preventing you from tuning your guitar by actually playing music, it seems to me you do not understand what performing is about, you prefer someone who performs from a crib sheet, rather than someone who performs 3 songs well, if you dont like it, vote with your feet and organise your own club.
