How do you determine if anything has 'real heritage in the folk tradition'? This is clearly going to be a very subjective judgement. The evidence presented by Forrest strongly suggests that the Morris has almost died out and been revived on several occasions in the past six hundred years and has changed its form significantly over that period. Seen in that context, the most recent revival is very much part of the folk tradition, albeit aided by much more powerful information recording and distribution technology than was available in earlier episodes.
