"In true folkloric terms a community can consist of as few a two people."
Who sez???
In terms of folksong, the community has always been considered of the type described by Laurence Gomme, George Ewart Evans, Estyn Evans, George Bourne et al. The songs (stories and lore) recorded the activities and reflected the values of the community that "worked, prayed, drank, socialised and were educated together - hardly something that can be done for two people.
Can you please point out where it is claimed that a community can consist of two people, folkloric or otherwise?
