I just looked at Shenandoah in the DT. (see link above)

This song has a beautiful melody but trivial words. And when you get into "the white man loved the Indian maiden," it becomes downright cringeworthy.

If you want to sing the beautiful song, learn "Across the Wide Missouri," which was sung by the Kingston Trio can easily be found on the Internet. It won't win the Pulitzer Prize, but it won't make you cringe, either.

Historical note: the Missouri wide today, but before it was channelized, it was three times wider. Also shallower and slower, except when it was flooding.
