I can't be the only one choking on the ease with which the original songwriter is dismissed. Without in any way diminishing the process of domestication and localisation of a song, its popularity must have been in large part due to the excellence of the original material.

By all means fetishise transference but 'anon' does not only mean unknown in the traditional context, it suggests the real fun started after it was written - not only a challenge to authorship but a complete dismissal of its importance.
