Try "The Vacant Chair." The last verse goes, "Sleep in peace, O early fallen,/ in thy green and narrow bed/ Dirges of the pine and cypress / mingle with the tears we shed." It's in the DT.

There's a wonderful spiritual called "I Don't Want to be buried in the Storm" which is not in the DT. I found it years ago in the Appendix or Notes or whatever, a separate book published with addenda to Carl Sandburg's American Songbag. I loved it and still sing it. Again, I'll type it in (and Bill can send the tune via some shareware tricks he knows) if you want. But Beware -- this one has probably been distorted by years and memory.
