Also, considering its large size, your would think there might be a couple of Jewish kids in the band who would be teed off.
As I mentioned in an earlier post, the article I read a year or more ago about this (IIRC) laid responsibility at the feet of the band director and the student drum major, and if I recall rightly, some of the section leaders. The article said there was quite a bit of coercion and “go along to get along” in the workings of the band plus possible loss of scholarships in order to force or enforce students to accept these abominable songs and lyrics. I suspect a google search might locate the relevant articles.
