Oh, and tangentially -- I didnt think "fair land o' Canaan" was something that would require bowdlerization. Perhaps I am being naive :) But I just read it as a religion-based sentiment/expression, and particularly one that African-Americans might use. I thought that Angel would change it because, even if it wasn't "too Black," then it at least might be an unfamiliar reference to his presumably largely Anglo-European audience. Just speculating here.
