I appreciate the the song Perhaps Love of John Denver.
In minute 2:04 he says while his songs are universal he can be with a Japanese audience, half of whom do not understand English, but can sing all of his lyrics.
John Denver also reminds me of the fact that huge numbers of German Americans changed there names during US wars against Germany. About lost German culture I wrote years ago at http://www.esperantofriends.blogspot.com/ He, of cause did it in the name of his singing career or that his name was "too long" according to http://en.wikipedia.org/wiki/John_Denver . He was born ..... HENRY JOHN DEUTCHENDORF JR., about as German a name as you can get. Deutchendorf means German Village.
