Hi it was more the history lesson I object too.
Also a lot of the time the object of the lecture is to justify the apropriation of a working persons music for the use of the educated classes.
After all the weaver,fisherman,ploughboy who probably made up or elaborated the song over the years was obviously not aware of its importance and value.
Merely using it as a means of entertainment in the dark dives and public houses that he frequented would indicate that high culture was beyond his comprehension.
Luckily a nice well educated person capable of understanding the true worth of such music and songs was able to save this peice for the delectation of all who like to listen to history lectures.
It puts me in mind of the British arriving in India and discovering awhole new sub continent,the fact that it was already populated by a whole load of highly cultured and educated races seemed to escape them completly.
