rm, i can only speak as a non-US citizen but i think there are similie-arities between willie nelson and gord as i know willie is a well-seasoned household name across the land with a universally recognizable small bag of tunes, not to mention 'voice'...of course there is a much larger bag of tunes that the non-masses have treated themselves to
however, but from what i've read of at various 'folk' sites and listened to over the past few years, i would put john stewart out there as a candidate
it hit me during show#301, @
