@John I remember when my American Grandma Dorcas (yes, that's actually her name), who couldn't carry a tune in a bucket if she tried, would sing the original German version of Brahms Lullaby, I remember when she pronounced "morgen früh", it sounded to me like she sang, "Morgan free". So maybe "glüh'n" would be something like "Glean", and "erblüh'n" would be something like, "air bleen"?
