The IFMC were happily going with thier definition when Douglas Kennedy, the then Director of EFDSS, proposed the addition of the third paragraph. It addresses, specifically, the issue of contemporary popular music.
Douglas Kennedy must have attended the congress in his capacity,asDirector of EFDSS.
EFDSS remit then, as it is now,was the preservation, encouragement promotion of International Dance and English Song[please note English Song]not International song.
Music includes both dance and song,yet his input effectively,affected International Folksong which was not his concern.other than how English Folk song was affected.
Tootler, you are quite right,revising would be better.
